The equation of a line in slope-intercept form is y = mx + c.
The slope is m and the y-intercept is (0,c).
5.3.56: y = 4x - 9
=> m = 4 and c = -9
The slope is 4.
The y-intercept is (0,-9).
5.3.57: y = 3
=> y = 0x + 3
m = 0, c = 3.
The slope is 0.
The y-intercept is (0,3).
5.3.59: 3y = 2x - 12
=> y = 2/3 x - 4
m = 2/3 c = -4
Slope is 2/3.
The y intercept is (0,-4).
(Note: The answer (0,-4) is definitely correct. If we substitute x = 0 in 3y = 2x - 12, we get 3y = -12 => y = -4.
Two suggestions: Remove spaces between - and 4 if any. Also try entering -12/3.)
