In order for a line to be perpendicular, its slope must be the negative reciprocal of the other line. We’re solving for the b part of y = mx + b
The new line = -4x + b
4 = -4(-2) + b
4 = 8 + b
b = -4
The equation of the line is y = -4x - 4
Answer:
True
Step-by-step explanation:
Firstly, “ % ” means percent, which, as it name says, is the amount of the number per 100 .
Take 5% for instance, 5 percent would mean 5/100
Likewise, x%=x/100
Now x% of y means x/100×y=xy/100
but also, y% of x means y/100×x=yx/100
and therefore these two are the same!
Answer:
multiply the legth times width
Step-by-step explanation:
Direct proportionality
y/x=k
-9/3=k
k=-3
so when y=18
18/x=3
cross multiply
3x=18
divide both sides by 3
3x=18
x=6
