Find the equation of a straight line parallel t... - JAMB Mathematics 2022 Question
Find the equation of a straight line parallel to the line 2x - y = 5 and having intercept of 5
A
2x + y = 5
B
2x + y = -5
C
2x - y = -5
D
2x - y = 5
correct option: c
If two lines are parallel then their slopes (gradients) will be equal.
Line 2x - y = 5
Equation of a straight line: y = mx + c
y = 2x - 5
line 2x - y = 5 has a gradient of 2
A parallel line with a gradient of 2 and intercept of 5
=> 2x - y = -5
=> y = 2x + 5
