<h3>1.) Combine x and 3x:</h3>
<em> - We combine the </em><em> variables because to get to the end sum of the equation, there can only be 1 variable. So to get the 1, you combine like terms. </em>
<em />
<h3>2.) Add 19 to both sides:</h3><em> - We do this to get 1 number left over. To do this you do the opposite of what you see. In this case we have a negative 19, so you add 19 on each side of the equals. </em>
<em />
<h3>3.) Divide both sides by 4:</h3><em> - We do this to get x alone. To do this you do the opposite of what you see. In this case we have </em><em> which is multiplying, so you divide by 4 on each side. </em>
<em />
So your answer is .

Answer:
y=-3x+7
Step-by-step explanation:
y=mx+b is the formula you are going to end up once completed.
This, by given two points:
(4,-5) (3,-2)
= Point-Slope Intercept Form
= After subtracting both from above
-3 = is your slope, decreasing.
Substitute -3 for y=mx+b
y=-3x+b
Use one of the given points (any) to find what b equals.
(4,-5)
x y
-5=-3(4)+b
-5= -12+b
7=b
Final Equation:
y=-3x+7
