the line has a slope of -7 and passes through the points to 2,-5

Answer 1

Start with y = mx + b.

 

The slope m = -7.

 Now plug on the x and y coordinates to solve for b.

 

-5 = -7(2) + b

 

-5 = -14 + b

 

b = 9

 

Slope intercept form is: y = -7x + 9

 

Rearranging to standard form means bringing the variables over to one side:

 

y + 7x = 9

 

Rearranging the terms, we get:

 

7x + y = 9
