Question

A line goes thru the point (-3, 2) and has a slope of 4. What is the y-intercept?

A) 0
B) -2/3
C) 14
D) -10

I am in need of assistance

Answer 1

b = 14

Explanation:

In order to find the y intercept of the problem, we will have to put the equation of the line in point slope form and solve for y.

Point slope form:
`y-y_1=m(x-x_1)`

Lets put the equation of the line in point slope form.

`y-2=4(x+3)`

Distribute 4

`y-2=4x+12`

Add 2 to both sides

`y=4x+14`

Now that the equation of the line is in slope intercept form, the y intercept is at the end of the equation, which is 14.

b = 14

Answer 2

14
