Question

Passes through (-5, 9) and (1, 3)​

Answer 1

equation is: y = -x+4

Explanation:

y = mx + b where m is the slope and b is the y intercept.

slope = (y2-y1)/(x2-x1)

= (9-3)/(-5-1)

= 6/-6

= -1

y = -1x + b

Plug in a point & solve for b

3 = -1*1 + b

3 = -1 + b

4 = b

equation is: y = -x+4
