What is x and y intercepts for y=x+7

X intercept is -7 and Y intercept is 7.

Step-by-step explanation:

In order to find  X intercept of an equation ,we put y =0

and for Y intercept we put x =0

therefore Y intercept of given equation  y = x+7 is

 plugging  x =0  in the equation ,we get

        y = 0 +7 = 7

       y = 7 ,Y intercept is 7

For X intercept ,we plug y =0

        0 = x+7

          x = -7

      So X intercept is  -7

And Y intercept is 7

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
