Question

5. What is an equation of the line in slope-intercept from?
m=3 and y-intercept is (0, 4)
A. y = 4x +3
B. y = -3x +4
C. y = 4x -3
D. y = 3x +4

Answer 1

The equation of a line is given by

y = slope*x + y-intercept, or

y = m*x + b.

Well, m=3, y-intercept = (0,4), so b=4, so the equation is:
D) y = 3*x + 4.

Answer 2

thanks i got that too :)
