6) Write an equation parallel to y = − x − 12 that passes through ( − 3 , − 4 ).

y=-x-7

Step-by-step explanation:

We know that parallel lines never touch and cross each other. This means that the slope for both lines MUST be the same.

y=-x+b

Now, all we have to do is to plug in the given point and solve for b, where the y-intercept will be different.

-4=-(-3)+b           [multiply]

-4=3+b                [subtract both sides by 3]

b=-7

With the y-intercept, we can find our equation.

y=-x-7

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
