Question

There is a line that includes the point (1,6) and has a slope of 4. What is its equation in

slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

y=4x+2

Explanation:

y-y1=m(x-x1)

y-6=4(x-1)

y=4x-4+6

y=4x+2

Answer 2

y=4x+2

Explanation:

So we start with the slope, which is bad.

But I have an idea

lets write it as

y=4x+? and since x=1 and y=6

6=4+?

Therefore, the y, intercept must be two
