Which equations below represent lines that are perpendicular to the line that contains (1, - 2) and (3,4)^ Select all that apply

Nady [450]

Answer:

Select all the lines with slope $-\frac{1}{3}$ .

Step-by-step explanation:

Use the slopes to help you answer this kind of questions.

The slope of the line going through: (1, - 2) and (3,4) is given by:

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

We plug in the coordinates to get:

$m=\frac{4--2}{3-1}=\frac{6}{2}=3$

All lines that are perpendicular to this line has slope $-\frac{1}{3}$ .

If f(x)=-3+7 and g(x)=-7+3, what is the value of f(-3) - g(3)

Andreyy89

F(x) = -3 + 7 = 4
g(x) = -7 + 3 = -4

f(-3) - g(3) = 4 - (-4) = 4 + 4 = 8
