Problem:
If the line L in the xy-plane has half the slope and twice the y-intercept of the line y=32​x+4, then an equation for L is
Answer Choices:
A. y=31​x+8
B. y=34​x+2
C. y=31​x+4
D. y=34​x+4
E. y=31​x+2
Solution:
The slope of the original line is 2/3 and the y-intercept is 4. So L has slope 1/3 and y-intercept 8.
