Step-by-step explanation:
Given the system of equations:


In order to find the y coordinate of the solution we must first find the solution to this system of equations. We first start by solving one of the given equations and then substitute the answer of that into the second equation and further solve to get the final answers.




















Hope this helps.
The slope of every horizontal line is 0 because that is based on the formula. If it's horizontal on the x axis for example, the point slope will be 0,0, also the horizontal line is the numerator, i think. And the undefined slope is vertical because it's the denominator.
Answer:
The correct answer is 20x-1
Answer:
a = -32
Step-by-step explanation:
-1/4a - 4 =4
Add 4 to each side
-1/4a - 4+4 =4+4
-1/4a = 8
Multiply each side by -4 to isolate a
-1/4 a * -4 = 8 *-4
a = -32
