Question 1013268
Parallel lines have the same slope.
.
y=mx+b, m=slope
.
y=2x+6, m=slope=2
.
So parallel line will have the form: y=2x+b
.
To find b, use the point (4,2):
x=4 and y=2
.
y=2x+b
2=2(4)+b
2=8+b
-6=b Use this in the equation for b.
.
y=2x+b
y=2x-6
.
ANSWER: Equation for the parallel line through (4,2) is y=2x-6
