Has slope 3 and passes through (2, 2)

y=3x-4

Step-by-step explanation:

Lets make this into y=mx+b form

m(slope)

b(y intercept)

y=3x+b

Now plug in 2 for y and 2 for x (since the coordinantes are 2,2)

2=3(2)+b

Simplify like terms

2=6+b

-4=b

So b=-4 and m=3.

You got your equation, y=3x-4

1/5^2 = 7.56/45

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
