Answer: D

Step-by-step explanation:

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

Step-by-step explanation:

Answer:

-11/12

Step-by-step explanation:

Add 5/8+3/4 (6/8) which is 11/8 and then get -2/3 - 5/6 which simplifies to -3/2

Multiply -3/2 by 4 to get it to like terms

11/8 / -12/8

Multiply and then simplify.

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.

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.

Answer:

Step-by-step explanation:

Answer:

B, y = 8/3x - 2/3

Step-by-step explanation:

parallel lines have the

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.

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.

(I honestly have no clue what she is doing but, its stupid)

Answer:

answer would be 120 degrees.

Step-by-step explanation:

because 4y+4+60=180

angle Q =4y+4

so 180-60=120

Answer:

-13

Step-by-step explanation:

-5y = 9 + 6

y = 15 / -5

y = -3

Now;

y - 10 = -3 - 10 = - 13

Answer: 2х+5y=25=  Slope = -0.800/2.000 = -0.400

 x-intercept = 25/2 = 12.50000

 y-intercept = 25/5 = 5

so slope form =0,400

x intercept form = 12.50000

y intercept =5

and the answer to 2x+3y=-1=  Slope = 1.333/2.000 = 0.667

 x-intercept = 1/2 = 0.50000

 y-intercept = -1/3 = -0.33333

Step-by-step explanation:  an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2x+5y-25  = 0 and calculate its properties

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

 y-intercept = 25/5  =  5

When y = 0 the value of x is 25/2 Our line therefore "cuts" the x axis at x=12.50000

 x-intercept = 25/2  = 12.50000

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 4.200. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 4.200 - 5.000 = -0.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -0.800/2.000 = -0.400  

Geometric figure: Straight Line

 Slope = -0.800/2.000 = -0.400

 x-intercept = 25/2 = 12.50000

 y-intercept = 25/5 = 5
