.
To find the intersection, begin by getting both equations into standard form.
.
y=4/3x+16/3
-4/3x +y = 16/3
multiply by 3
-4x + 3y = 16
.
y=3/2x+1
-3/2x + y = 1
multiply by 2
-3x + 2y = 2
.
Now we have a system of equations
.
-4x + 3y = 16
-3x + 2y = 2
.
Multiply the first equation by 3 and the second by 4, then subtract.
.
-12x + 9y = 48
-12x + 8y = 8
--------------
y = 40
.
substitute to find 'x'
.
-4x + 120 = 16
-4x = -104
x = 26
.
The point of intersection is (26,40).
