i need help with math equation

Question

Find the equation in slope-intercept form of the line with slope -8 that passes through the point (3,5).  

Answer 1

y=mx + b where m=slope and b=y intercept

y=-8x + b. plug in the point to solve for b

5=-8(3)+ b

b =5+24 = 29

y=-8x + 29 is the line with slope =-8 and through the point (3,5)
