y=mx+b is the equation of a line;
m=slope , b= y-intercept
m=4 ; so we have : y=4x+b
We are give a set of points which it passes through, we can simply plug them in:
-2 = 4(3)+b (3 is the x and -2 is the y)
We get -2 = 12 +b .... -14=b
our final equation is : y=4x-14
$790 because it would be 79 times 10
The answer is A. Y=square root of 2x
Three variable terms appear in this expression. Although 9xy has two variables, they combine to make one term.
