Which line has a slope of 0.625, and which line has a slope of 1.6?
Explain why the slopes of these lines are 0.625 and 1.6.
Answers
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b; where y and x are variables, b is the y intercept (i.e. value of y when x is zero), m is the slope of the line.
The slope of a line passing through the points [tex](x_1,y_1)\ and\ (x_2,y_2)\ is:[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let the point where the two lines intersect be the origin (0, 0).
Line 1 passes through (0, 0) and (8, 5). Hence:
slope of line 1 = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{5-0}{8-0} =0.625[/tex]
Line 2 passes through (0, 0) and (5, 8). Hence:
slope of line 2 = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{8-0}{5-0} =1.6[/tex]

Lisa collected data on the grams of fat and the grams of carbohydrates in 10 sandwiches at a popular restaurant. The table below represents the data she recorded.
Which linear equation best fit Lisa’s data?
A. y=0.5x + 23
B. y=23x+ 0.5
C. y=1.5x+ 27
D. y=27x + 1.5
Answers
Answer:
A. y=0.5x + 23Step-by-step explanation:
Take two random pairs from the table and find the formula:
(12, 32) and (24, 36)Find the slope:
m = (36 - 32)/(24 - 12) = 4/12 = 1/3Find y-intercept:
12*1/3 + b = 32b = 32 - 4 = 28b = 28The line is:
y = 1/3x + 28The best fit is A. y = 0.5x + 23, the other options have too much of difference in the slope or y-intercept

I need help with a geometry problem! It’s about reflection
Answers
Step-by-step explanation: Here, we're asked to reflect ΔQRS over
the x-axis so we begin by reflecting point Q over the x-axis.
Since point Q is 2 units below the x-axis, point Q will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as Q' which is the ordered pair (1, 2).
Next we reflect point R over the x-axis.
Since point R is 2 units below the x-axis, point R will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as R' which is the ordered pair (3, 2).
Now connect the points to get our reflection.
Next we reflect point S over the x-axis.
Since point S is 6 units below the x-axis, point S will reflect
over the x-axis to a position 6 units above the x-axis.
We label this point as S' which is the ordered pair (1, 6).

The value of a = -12
Step-by-step explanation:
Given the equation
[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]
Determining the value of a
Given the equation
[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]
Apply the exponent rule: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]\:8^{-55-a}=8^{-43}[/tex] ∵ [tex]\frac{8^{-55}}{8^a}=8^{-55-a}[/tex]
[tex]-55-a = -43[/tex]
Add 55 to both sides
[tex]-55-a+55=-43+55[/tex]
Simplify
[tex]-a=12[/tex]
Divide both sides by -1
[tex]\frac{-a}{-1}=\frac{12}{-1}[/tex]
Simplify
[tex]a=-12[/tex]
Therefore, the value of a = -12

im not sure if im correct but y could be 6 because if u multiply 4 by 6 its 24 and x is 2 so 2 times 2 is 4 and if we subtract 4 from 24 its 20 plus 6 its equals 26
how to show work:
y=6 x=2
4y - 2x + 6 = 26
4x6=24 - 2x +6 =26
24 - 2x2=4 +6 =26

Lori graphed f(x) = -34x – 1 and g(x) = -4f(x) on the same coordinate grid. Which statement below incorrectly describes how the graphs of f(x) and g(x) are related?
A:The graph of f(x) is less steep than the graph of g(x)
B:The graph of f(x) is shifted 4 units up to create the graph of g(x).
C:The graph of f(x) has the same x-intercept as the graph of g(x)
D:The y-intercept of f(x) is 5 units below the y-intercept of g(x).
Answers
Answer:
C
Step-by-step explanation:
I’m on a test and graphed this
The statement that incorrectly describes how the graphs of f(x) and g(x) are related is B:The graph of f(x) is shifted 4 units up to create the graph of g(x).
The function f(x) is given as:
f(x) = -34x – 1
The function g(x) is given in terms of f(x) as:
g(x) = -4f(x)
Substitute f(x) = -34x - 1 into g(x)
g(x) = -4(-34x - 1)
g(x) = 136x + 4
Find the x-intercept of f(x)
Let f(x) = 0
0 = -34x - 1
x = -1/34
The x-intercept of f(x) = (-1/34, 0)
Find the x-intercept of g(x)
Let g(x) = 0
0 = 136x + 4
x = -4/136
x = -1/34
The x-intercept of g(x) = (-1/34, 0)
It is true that the graph of f(x) has the same x-intercept as the graph of g(x)
The y-intercept of f(x) is -1 and the y-intercept of g(x) = -4
It is true that the y-intercept of f(x) is 5 units below the y-intercept of g(x)
The slope with a greater absolute value is steeper.
The slope of g(x) is greater than that of f(x), therefore, the graph of g(x) is steeper.
The only incorrect statement is option B. The graph of f(x) is shifted 4 units up to create the graph of g(x)
