Since we're adding fractions we'll need to make the denominator the same

5 fits into 15 three times

so we'll need to multiply both the numerator and denominator of -2/5 by 3

-2/5 becomes -6/15

now we can solve

11/15 + -6/15 = 5/15

5/15 can be written as 1/3 in simplified form

Answer:

Graph y = 2x

Step-by-step explanation:

First, let's get the equation into standard form. Distribute the 2 on the right.

$y-4=2x-4$

Next, we want the variable "y" to be alone, so we at 4 to both sides.

$y-4+(4)=2x-4+(4)\\\\y=2x$

That is our equation in standard y = mx + b form. "m" is our slope, while "b" is our y-intercept. Above , we don't have a value for b, therefore the line passes through the origin.

We do, however, have a slope, which can be thought of as $\frac{rise}{run}$ or rise over run. To represent this, we can rewrite our slope as:
