Algebra practice question

Answer: 9

Line l has slope 3/4, so m has slope −4/3. Then 1 = (−4/3)(6) + b gives b = 9.

Common wrong answers

If you answered -7

−7 uses the slope 4/3 instead of −4/3.

If you answered -3.5

−3.5 uses the slope 3/4 of line l.

If you answered -6

−6 is the y-intercept of line l.
