Question

if the equation y=-4x+b represents the line that passes throught the point (1,4) determine the value of the y-intercept

Answer 1

y-intercept (0, 8)

Explanation:

Plug in (1,4) --> (x,y) and solve for b (y-intercept):

y = -4x + b

4 = -4(1) + b

4 = -4 + b

b = 8

Therefore the y-intercept is (0, 8)
