The answer would be 1 by 3 y to the first power
Answer:

Step-by-step explanation:
10a + 9b = 3c
Subtract 9b to isolate the variable a.
10a = 3c - 9b
Now we need a singular a, so divide equation by 10.

So that's how you do it.
4x - 3y = 8 ⇒ 8x - 6y = 16
5x - 2y = -11 ⇒ 15x - 6y = -33
-7x = 49
-7 -7
x = -7
4x - 3y = 8
4(-7) - 3y = 8
-28 - 3y = 8
+ 28 + 28
-3y = 36
-3 -3
y = -12
(x, y) = (-7, -12)
To use elimination you have to multiply the first graph by 2 and the second graph by 3 so that the two y-axis can be equal to -6. Then you do the rest to find the answer of the x-axis and the y-axis.
Slope is (change in y)/(change in x). If you have a slope of -2/3 the change in y is -2 and the change in x is 3. Find the point (-2, 1) on the xy plane. Change the y component by -2 (move down 2 grid lines) then change the x component by 3 (move to the right 3 grid lines). If you repeat this process in both directions then draw a line through the points you'll have a line with slope -2/3 which passes through the point (-2, 1). The equation of this line is: y=-2/3x-1/3
