Step-by-step explanation:
Is this rsm??
Just wanted to see because I have that problem too
Answer:
The answer is B y = 1.5x – 4.5
Step-by-step explanation:
The equations above are all in the format
, where
= the gradient, or slope.
So, in the first question,
, the gradient would be 4, because 4 is
in this equation (the number before the
).
The gradient of a line perpendicular to this line is equal to the negative reciprocal of the gradient of the line. A better way to explain it is if
= the gradient of the line and <u />
= the gradient of the perpendicular line then:
So in the first question, the gradient of the perpendicular line is
.
