What is the slope of the line passing through the points (0, 4) and (6, 13)

skelet666 [1.2K]

Answer:

The slope is $\frac{3}{2}$

Step-by-step explanation:

Hi there!

We are given the points (0, 4) and (6, 13)

We want to find the slope of the line containing these two points

Slope (m) is the steepness of the line. When calculating from two points, you use the equation $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

Although we have what we need to find the slope, let's label the values of the points to avoid confusion and mistakes.

$x_1=0\\y_1=4\\x_2=6\\y_2=13$

Substitute these values into the equation

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

m= $\frac{13-4}{6-0}$

Subtract

m= $\frac{9}{6}$

Simplify

m= $\frac{3}{2}$

The slope of the line is 3/2

Hope this helps!

A small garden measures 8 ft by 7 ft. A uniform border around the garden increases the total area to 110 ft 2. What is the width

Alik [6]

Answer: 3

Step-by-step explanation:

You can answer this question by using the equation

(8+x)(7+x)=110

The x represents the width, as we do not know the area. If you simplify the equation, it becomes 56+15x+x2=110.

If you move all the terms to the left side, and rearrange it, it can become x^2+15x-54=0

This can be simplified into (x-3)(x+18)=0

This equation makes it so that x is either 3 or -18. It is not possible for a width to be -18, so the width must be 3.

W-5=5
W= 5+5 (bringing -5 to the other side, it becomes +5)
