Question

Which ordered pair represents the yintercept of the graph of the equation

y=-4x - 7?
A. (-4,0)
B. (0, -4)
C. (0, -7)
D. (-7,0)

Answer 1

C

Explanation:

Put x=0 to get Y intercept

Y=-4x-7

Y=-4(0)-7

Y=-7

Therefore the coordinate is (X,Y)=(0,-7)

Answer 2

C

Explanation:

The equation of a line in slope- intercept form is

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

y = - 4x - 7 ← is in slope- intercept form

with y- intercept c = - 7 ⇒ (0, - 7 ) → C
