What is the equation of the line in slope intercept form?

Given points are (-1,-1) and (-3,5).

Now we have to find equation of line in slope intercept form y=mx+b

Let's find slope (m) first using formula :

Now we can plug m=-3 and any point says (-3,5) into formula y=mx+b

5=-3(-3)+b

5=9+b

5-9=b

-4=b

Now plug m=-3 and b=-4 into formula y=mx+b. We get:

y=-3x-4

Hence final answer is y=-3x-4.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

your answer is -9
