Answer:
y = 4x - 27
Step-by-step explanation:
The point (8,5) contains and x and y on the line. The x is 8 and the y is 5. Using this and the slope given we can write the equation. We need to solve for b.
y = mx + b
5 = 4(8) + b
5 = 32 + b Subtract 32 from both sides of the equation
-27 = b
y = mx + b
y = 4x - 27

Step-by-step explanation:
y-y1=m(x-x1)
where y1=5,x1=8 and m=4
y-5=4(x-8)
y-5=4x-16
y=4x-16+5
y=4x-11
