Look at the screen shot teach me how to do this thank you.

Slope intercept form (y = mx + b) =

X intercept (slope):

Y Intercept:

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y and solve for  x.

To find the y-intercept, substitute in  0  for  x and solve for  y.

Hope this helps! :D

Step-by-step explanation:

solve for y

isolate the y variable to one side

let's first add 7 to both sides of the equation

sevens on the left side of the equation cancel so we get

Now let's divide everything in the equation by 3 to further isolate the y variable

The threes on the left hand side of the equation cancel

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
