Question

Given the point (-1, 1) and the slope 4, write the equation of the line in slope-intercept

Answer 1

Answer:

y=4x+5

Step-by-step explanation:

Slope intercept is y=mx+b. y=y-value, m=slope, x=x-value and, b=y-intercept.

With the information given we can plug some numbers into the equation: 1=4(-1)+b

Solving for b we get, {4(-1)=-4, -4--4=0, 1--4=5} 5=b. Therefore, B is equal to 5.

Plug that into the original problem: y=4x+5 and re-add the plot point 1=4(-1)+5 and solve to verify the answer.

After solving, {4(-1)=-4+5=1} we get  1=1 which is a true statement.
