Answer:
Gradient of parallel line= 7
Gradient of perpendicular line
Step-by-step explanation:
The equation of the line is already in slope-intercept form (y= mx +c). This means that the coefficient of x is the gradient and the constant -3 is the y-intercept of the line.
y= 7x -3
Gradient= 7
Parallel lines have the same gradient.
Thus, the slope of the line parallel to this line is also 7.
The product of the gradients of 2 perpendicular lines is -1.
(Gradient of perpendicular line)(7)= -1
Gradient of perpendicular line
= -1 ÷7
Answer:
A) 9
B) -4x
C) 11x
D) 5
Step-by-step explanation:
You want to make both sides equal because when both sides are equal there are infinitely many solutions.
