Question

What ordered pair represents the

y-intercept of the graph of 5x + y = 8?

A (0, −8) C (0, 8)
B (0, 5) D (0, −5)

Answer 1

C

Explanation:

The equation of a line in slope- intercept form is

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

Rearrange 5x + y = 8 into this form by subtracting 5x from both sides

y = - 5x + 8 ← in slope- intercept form

with c = 8 ⇒ (0, 8 ) → C
