Write an equation of the line that has slope 3 and y-intercept (0, -0.5).
Hint
Use slope-intercept form; m = 3, b = -0.5
Answer
y = 3x – 0.5
Write an equation of the line that passes through (4, 8) and (6, 14).
y = 3x – 4
Write an equation of the line that passes through (3, 2) and is perpendicular to y = 5x + 3.
The slope of a line that's perpendicular to another line equals the negative reciprocal of the first line: .
Write an equation of the line that has b = 3 and passes through (2, 1).
We can't use the slope-intercept equation, because we don't have the slope. However, the y-intercept can be rewritten as (0, 3).
y = -x + 3
Write an equation of the line that has passes through (6, 4) and (1, -1).
y = x – 2
