Question

A line has a slope of 3/2 and has a x-intercept of 2 . What is the y-intercept of the line?

Answer 1

- 3

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)/(2)` x + c ← is the partial equation

To find c substitute the x- intercept (2, 0 ) into the partial equation

0 = 3 + c ⇒ c = 0 - 3 = - 3 ← y- intercept
