Which is a correct way to test whether two variables representing numbers, numone and numtwo, are equal?

You use variables for the equation and after you find out the variables you set them equal to each other and see if they are equal

Answer:

m = y2 - y1 / x2 - x1 -8 - (-5)/1-3

-8 +5/1-3

-3/-2

slope is 1 1/2

What is the equation of the line that passes through (7, 4) and (4, -2)?

erastova [34]

Solution:

we have been asked to find the equation of the line that passes through (7, 4) and (4, -2).

First we will find the slope of the line using the formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Plugin the given values we get

$m=\frac{-2-4}{4-7}=\frac{-6}{-3}=2$

Now using the point slope form of a straight line

$(y-y_1)=m(x-x_1)$

Plugin the values

$(y-4)=2(x-7)\\ \\ y=2x-14+4\\ \\ y=2x-10\\$

Hence the correct option is a.
