Answer 2

Answer:

Step-by-step explanation:Rearrange the equation to slope-intercept form,  

y  =  m x + b , where  m  is the slope and  b  is the y-intercept.

x − y = 7  

Subtract  x  from both sides.− y = − x + 7

Multiply both sides by  − 1 .

y = x − 7

Since this is a linear equation, only two points are needed.

Table of Points  x = 0 , y = − 7 (y-intercept)

x = 7 , y = 0  (x-intercept)

Plot the points on a graph and draw a straight line through the points.
