What is the slope of the line that passes thru (7,2) and (9,6)?

1 answer:

8 0

Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:

y2-y1/x2-x1

Plug in the values.

6-2/9-7 =

4/2 =

2

Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.

Hope this helped!

Answer:

$\displaystyle 79°$

Step-by-step explanation:

The m∠x is 79°, according to the Alternate Exterior Angles Theorem.

I am joyous to assist you anytime.

* That does NOT look like an acute angle because 79° is considered an acute angle, since it is less than 90°.

Write the slope-intercept form of the equation of the line described.

yarga [219]

The equation for a line is y=mx+b

m is the slope, so when a line is perpendicular to another line is has a slope which is an opposite reciprocal, so change the -1/2 (the slope of the other line) to 2/1 or just 2

so m=2

now you need to plug in the point they give you for x and y

y=mx+b
4=2(4) + b
simplify
4=8 + b
subtract 8 over
-4 = b

now that you know that slope (m) and the y-intercept (b) you can plug those two numbers into the original equation for the answer

y= 2x -4
