Question

The equation of a line is y = 3 - 4x What is the y-intercept of the line?

help :')​

Answer 1

The y-intercept of the line is 3.

Explanation:

Formula: y = mx + b

y = 3 - 4x

y = -4x + 3

On the formula, "b" means y-intercept. Therefore, the y-intercept of the line is 3.

Answer 2

y-intercept is 3

The point where the line intercepts the y-axis is (0, 3)

Explanation:

Slope-intercept form of a linear equation:
`y=mx+b`

(where
`m` is the slope and
`b` is the y-intercept)

Given equation of line:
`y=3-4x`

Rearrange:
`y=-4x+3`

Therefore, the slope of the line is -4 and the y-intercept is 3.

FYI the line intercepts the y-axis when x = 0, so you can input x = 0 into the equation to find y ⇒ (0, 3)
