Answer:

c) $y=\frac{2}{3} x+9$

Step-by-step explanation:

The way I solve these is...

First, you look at where the line crosses the y-axis because that's your b in the y=mx+b equation. Which is 9

Then I find a point where the line passes thru so for example, (-6,5) Remember that x point is always before the y.

From there I determine if the line is positive or negative, this one's positive because the line goes up from left to right, if it were going up from right to left, then it'd be negative.

So knowing it's positive we count the points up and to the right until reaching the next point. So first go up 2 points and then right 3.

Knowing this, remember that it's always rise over run for the slope, so we rose 2, and ran 3. so, the slope is 2/3

This gives us our equation of $y=\frac{2}{3} x+9$

Answer:

x=-9

Step-by-step explanation:

first you make the coefficients equal to each other by doing a common factor which in this case is 5. Then you have to do the variable for each time the common number is repeated which is 5^x * 5^x= 5^(x+3)*5^(x+3)*5^(x+3) This would make it equal to 5^2x=5^(3x+9). Since the non exponents are common factors you can get rid of them and solve for the exponent by doing 2x=3x+9. You solve that equation to get x=-9.
