Question

2. Question 3

What is the y-intercept of a line that has a slope of -3 and passes through point (0, -7Y?
A. -7
B. -3
C. 0
D. 4

Answer 1

A

Explanation:

the equation of a line in slope- intercept form is

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

here m = - 3 and crosses the y- axis at (0, - 7 ) ⇒ c = - 7

that is the y- intercept c = - 7
