Y = 20x + 7 for instance
then just substitute the values
Answer:
Step-by-step explanation:
4x+y=14
x-2y=8
then;
x=8-2y
substitute;
4(8-2y)+8-2y=14
32-8y+8-2y=14
40-10y=14
26=10y
y=2.6 , work out 4x+2.6=14 to get x
ABOUT SLOPE INTERCEPT FORM:
- y = mx + b
- m represents the slope
- b represents the y-intercept
You have to get y by itself:
5x + 8y = 16
-5x -5x
<u>8y = -5x + 15</u>
8 8
y = -5/8x + 15/8
OR
I you wants to simplify 15/8, it's this:
y = -5/8x +1.875
HI!!! Really really sorry if I'm incorrect...
