Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)
Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.
[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.

4) Oceanside Bike Rental Shop charges $17 plus $6 an hour for renting a
bike. Tim paid 59 dollars to rent a bike. For how many hours did he check
out the bike?
Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours

What is the slope of a line that contains the following points (17,-12) and (17,8)
Answer:
no slope
Step-by-step explanation:
y2-y1/ x2-x1
8-(-12)/17-17 = 0
The line containing (17, -12) and (17, 8) has no slope.
The line is a vertical line with an x-intercept at x = 17.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
A line contains two points.
(17, -12) and (17, 8).
Consider,
(17, -12) = (a, b) and (17, 8) = (c, d)
The slope of the line.
Slope:
= (d - b) / (c - a)
= (8 - (-12)) / (17 - 17)
= 8 + 12 / 0
= 20 / 0
= undefined.
This means there is no slope for the line that contains (17, -12) and (17, 8).
The line is a vertical line intercepting at x = 17.
Thus,
The line containing (17, -12) and (17, 8) has no slope.
The line is a vertical line with an x-intercept at x = 17.

Step-by-step explanation:
Bob has 10 apples after 4 hours he has 6 apples. Find the slope l the line that indicates the rate that bob eats apples at.
Answer:
y= -x + 10
Step-by-step explanation:
At 0 hours = Bob has 10 apples
At 4 hours = Bob has 6 apples
In 4 hours Bob has eaten 4 apples
Using linear graphs where y = the apples remaining and x = the hours passed
y = mx + c
We already know some coordinates:
(0,10) - 0 hours 10 apples remaining
(4,6) - 4 hours 6 apples remaining
c is the y intercept and m is the gradient
We already have the y intercept (where x = 0) which is (0,10)
So first part of our rule is done: y = mx + 10
The gradient is rise / run
Rise = -4 and Run = 4
-4/4 = -1
So the gradient is -1 and we add that to our rule
So final rule is y = -x + 10

8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.
The slopes of parallel lines will be same.
Firstly let us find y intercept.
2=8/3(1)+b
2-8/3=b
-2/3=b
Hence, 8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.
