Answer:
[tex]\huge\boxed{\sf b = 28}[/tex]
Step-by-step explanation:
Point (x,y) = (2,20)
So, x = 2 and y = 20
Also,
Slope = m = -4
Slope-intercept equation:
y = mx + b
Where b is y-intercept.
Put the above given data in this equation.
20 = (-4)(2) + b
20 = -8 + b
Add 8 to both sides
20 + 8 = b
28 = b
b = 28
