Answer:

3x = 27

Step-by-step explanation:

The addition property of equality, which is used to justify this step in the proof, states that we can add the same number to both sides of an equation and maintain equality. The only number we would want to add in this equation to solve it would be 1 (adding one cancels the subtracted 1); doing so cancels it on the left and gives us 27 on the right.

Answer:

y=x+2

Step-by-step explanation:

the standard form is y=mx+b where m is the slope and b is the y intercept

TO FIND THE SLOPE: we take the x and y intercepts as a fraction. in this case the line touches the y axis (vertical) at point/value 2 and the x axis at point 2 as well. This means the slope is 2/2x which can be simplified to 1x or just x.

TO FIND THE Y INTERCEPT: we find where the line touches the y axis at point 2.

the slope is plugged into the m of the equation and the y intercept is plugged into the b of the equation.
