Answer: y=-2x+7

Step-by-step explanation:

First we need to find the slope. We can do this by appling the formula (y2-y1)/(x2-x1).

(3-(-1))/(2-4)=4/-2=-2

Now that we have the slope, we can use the slope and a coordinate point and plug it into point-slope form.

y-3=-2(x-2)

y-3=-2x+4 Isolate y for slope-intercept form.

y=-2x+7

Which pairs of variables have a linear relationship? Select

Neko [114]

Answer:

Side length and perimeter of 1 face

Area of 1 face and surface area

Step-by-step explanation:

Suppose you are given cube with side length of x units.

Then

Side length = x units

Perimeter = 4x units

Area of 1 face $=x^2$ square units

Surface area $=6x^2$ square units

Volume $=x^3$ cubic units

A linear relationship is any equation that, when graphed, gives you a straight line.

Consider all options:

A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function $y=kx$ is a straight line.

B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation $y=kx^2$ .

C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation $y=kx^{\frac{3}{2}}$ .

D. Area of 1 face and surface area is a linear relationship, because the graph of the function $y=kx$ is a straight line.

E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation $y=kx^3$ .
