Answer:
y = -12x - 77
Step-by-step explanation:
The standard form of the equation is expressed as y = mx+b
m is the slope
Given the coordinate (-7, 7) and (-6, -5).
m = -5-7/-6+7
m = -12/1
m = -12
Get the intercept b
Substitute m= -12 and (-7 7) into y = mx+b
7 = -12(-7) + b
7 = 84 + b
b = 7 - 84
b = -77
Get the required equation
y = mx+b
y = -12x +(-77)
y = -12x - 77
This gives the required equation
