Question

1. For the line y = 2x + 4. The y-intercept is [a] and the slope is [b]. What is b?

Ob=-2
b=4
Ob=0
b=2

Answer 1

b = 2

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 4 ← is in slope intercept form

with slope m = 2 and y- intercept c = 4

We are told for this question that b is the slope , so

b = 2
