Question

A line that includes the point (-1,5) has a slope of 4. What is its equation in slope-intercept
form?

Answer 1

Answer:

y=4x+9

Step-by-step explanation:

The slope intercept form is $y=mx+b$

So m=4 and we plug it into the equation $y=4x+b$

Since there are x point is -1 and y point is 5 we plug those in replacing the corresponding variables $5=4(-1)+b$

So the equation becomes $5=4+b$

We add 4 to both sides $5=4+b\\+4=+4$ so 9 equals b

Then we rewrite the whole equation as $y=4x+9$
