Question

Write an equation in slope-intercept form of the line that passes throught the point and given slope: (12, 5) ; m = -3

Answer 1

Slope intercept form: 
y=mx+b
m=slope
b=y-intercept

y=-3x+b

Plug in the given coordinate and solve for b (12,5) 
5=-3(12)+b
5=-36+b 
41=b 

Final answer: 
y=-3x+41
