Write the slope-intercept form of the equation for the line. a. y=-8/7x-3/2 b. y=-3/2x+7/8 c. y=-7/8x-3/2 d. y=7/8x-3/2

C

Step-by-step explanation:

The slope intercept of a line is y=mx +b where

This graph crosses the y-axis (the vertical line) halfway between -1 and -2. This  is -3/2. This means only answers a, c, and d are options.

The graph moves up from -3/2 to its next point at (-4,0). We calculate the slope using:

Slope:

We substitute and

This decimal is equivalent to -7/8. This means C is the answer.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
