Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
