Question

Has a slope of 1/2 and passes through the point (-2,4)

Answer 1

y =
`(1)/(2)` x + 5

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 =
`(1)/(2)` , then

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

To find c substitute (- 2, 4) into the partial equation

4 = - 1 + c ⇒ c = 4 + 1 = 5

y =
`(1)/(2)` x + 5 ← equation of line
