If x and y vary directly and y is 40 when x is 10, find y when x is 15.

Answer:

y is 60 when x is 15

Step-by-step explanation:

the ratio of x to y is 1:4

6/7 equals 18 over Y +15

Y= 3
Y=13
Y= 6
Y= 3.2

Find the slope (in reduced form) between the points (4, –6) and ( –2, 8).

18 is 40% of what number?

Jabari had two equations to solve. Both had two unknowns, x and y. Jabari could use them to solve each other. That's called (_______). Jabari decided to (_______) using the substitution method. First, he had to turn the x's in one equation into y's. He subtracted 2y from both sides of the first equation x+2y = 4. This made x = 4−2y.
Next, he substituted the expression 4−2y for x in (_______). Now he had (4-2y)−2y = 6.
Jabari saw that the two 2y's were like terms. He knew that collecting like terms is a way to (_______). He combined the y's to get 4−4y = 6.
From there, he subtracted 4 from both sides to get −4y=2. Now it was easy to evaluate the expression down to a single value. The problem's solution was (_______).
