Question

4

What is the y-intercept of the line
y = -3x + 1?
A (0, 1)
B (1,0)
c (0, -3)
D (-3,0)

Answer 1

A

Explanation:

The equation of a line in slope- intercept firm is

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

y = - 3x + 1 ← is in slope- intercept form

with y- intercept c = 1 ⇒ (0 , 1) → A

Answer 2

B.

Explanation:

Comparing the equation with standard one we get

Slope=-3

And

Y-intercept=1

Y intercept is the point where y becomes zero hence here 1 is x coordinate while y coordinate is 0

So the point is (1,0)
