Answer 1

Answer:  y = 1/2x -8  

Step-by-step explanation:

The equation will be in slope intercept form which uses the formula  y= mx +b   where m is the slope and b is the y-intercept and those are the only numbers need to write the equation.

The points are (2,-7) (8,-4) to find the slope using these points,find the change in their y values and divide it by the change in the x values.

-7- (-4) = -3

2 - 8 = - 6

-3/-6 =   1/2  

So in this case the  slope is 1/2, now input it into the equation and use one of the points coordinates to solve for b the y intercept.

-7 = 1/2(2) + b  

-7 =  1 + b

-1     -1

b = -8  

The y intercept is -8 so we will have the equation y = 1/2x -8
