The gradient of this line is 9 so the gradient of the perpendicular line is -1/9 (the two perpendicular gradients must multiply to get -1).
The equation of a line is y=mx+c
where m is the gradient and c is the y intercept
We can then just substitute values in:
y = -1/9(x) -2
Answer:
B
Step-by-step explanation:
1+1=2
But 2x has to stay the same
46/45. do u know how 2 do it? hope u do
-21 - 7x = 8x + 24
add 21 to both sides
-7x= 8x + 45
subtract 8x from both sides
-15x= 45
divide both sides by -15
x= -3
Hope this helps! :)
