Y = mx+b (slope intercept form). I imagine the point is (2,2) and m = 0. So the answer is y = 2. A sketch would be a horizontal line on the x-y plane going through (2,2).
Let's start with the x coordinates.
-8 is on the left, and -4 to the right, so that will help organize this.
the line goes from -8,-9 to -4,-8. it moved 4 over the x axis and rose 1 over the y axis.
rise/run so 1/4 is the slope.
y=(1/4)x - 7
Square root acts like a variable, so since there are 12 edges you want to distribute one length of an edge by 12. in the end youll get 144 + 120 square root 6
Answer:
(3, 6); (-3, 18)
Step-by-step explanation:
We equate the 2 expressions in x :-
x^2 - 2x + 3 = -2x + 12
x^2 - 2x + 2x + 3 - 12 = 0
x^2 - 9 = 0
(x - 3)(x + 3) = 0
So x = 3 or -3.
When x = 3, f(x) = -2(3) + 12 = 6.
When x = -3, f(x) = -2(-3) + 12 = 18.
