Question

Which of the following is the equation of a line in slope-intercept form for a line with slope =4 and y-intercept at (0,2)

Answer 1

y=4x+2

Explanation:

y-y1=m(x-x1)

y-2=4(x-0)

y-2=4(x)

y-2=4x

y=4x+2

Answer 2

Y = 4x +2

Explanation:

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