There's a pair of points (3,5), (x,15) and a slope of 2 how do I find x

You have the slope and you have two points, so you can use the slope equation to find x.

So your answer is x = 8.

x =7

Step-by-step explanation:

slope m = ( y2-y1) / (x2-x1)

for points (3,5) and (x,15)

that will be m= (5-15)/(3-x)

so (5-15)/(3-x) =2

-10 / (3-x) = 2 / 1 cross multiply

-10 = 2(3-x)  divide both sides by 2

-5 = 3 -x

x= 3+5 =8

d) 48

you probably already have the answer but anyways it's b. 15.0
