Question
Find the slope, X-intercept, Y-intercept of the following line:
3x − y − 9 = 0
Solution
Given equation of the line is 3x − y − 9 = 0.
Comparing this equation with ax + by + c = 0, we get
a = 3, b = – 1, c = – 9
∴ Slope of the line = `(-"a")/"b" = (-3)/(-1)` = 3
x-intercept = `(-"c")/"a" = (-(-9))/3` = 3
y-intercept = `(-"c")/"b" = (-(- 9))/(-1)` = − 9
