State the slope and y-intercept
1 answer:
Let's get this equation into a usable format, which is <em>y=mx+b</em><em /> (where m is the slope and b is the y-intercept), before graphing.
First, we move our x terms onto one side, so that the y terms are on one side, and the x terms on another side. Keep in mind that this will negate (multiply by -1) the x term we move.
<em>2y = -5x - 10</em>
Then we isolate y. We'll do this by dividing by 2.
<em>2y/2 = -5/2x - 10/2</em>
y = -5/2x - 5
We now have the equation in y=mx+b format. We can now graph (it should look something like the one below).
Slope: -5/2
Y-Intercept: -5

Answer:
Step-by-step explanation:
When simplifying an exponent a way to do is to expand the exponent. This means that it will now be
Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1
When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is
