what is the intersection of y=2x-8 and y=-2/3x??
please help me im having a very harddddd time with this??!! ( :
1) y = 2x - 8
2) y = -2/3 x
Y will be the same value in both equations, so set the
equations equal to each other and solve for x.
2x - 8 = -2/3 x
2x + 2/3 x = 8
8/3 x = 8
x = 8 * 3/8
x = 3
Use equation 2 to solve for y.
y = -2/3 x
y = -2/3 * 3
y = -2
The intersection is the point where x and y satisfy
both equations: (3, -2)
1) y = 2x - 8
-2 = 2(3) - 8
-2 = 6 - 8
-2 = -2
2) y = -2/3 x
-2 = -2/3 (3)
-2 = -2
