Hello!

To find the slope of the line given two points, you use the formula y2-y1/x2-x1. Each ordered pair can represent either the 1's or the 2's, and the slope will be the same. We will have (4,5) be (x1,y1) and (9,7) be (x2,y2). Now we will plug it into the equation.

7-5/9-4
2/5


Just to check, we will switch the ones and twos.

5-7/4-9
-2/-5
2/5

The slope of the line is 2/5.

I hope this helps!

The measurement of the complement of an angle exceeds the measure of the angle by 25%. Find the measurement of the angle and its
tester [92]
Let the angles be A and C 

<span>Complimentary angles, therefor </span>
<span>A + C = 90 </span>

<span>The measurement of the complement of an angle exceeds the measure of the angle by 25% (you used a % sign so I'll use % instead of degrees) </span>
<span>C = 1.25A </span>

<span>Substitute </span>
<span>A + 1.25A = 90 </span>
<span>2.25A = 90 </span>
<span>A = 40º <----- </span>
<span>C = 50º <----- </span>
<span>------------------------------ </span>

<span>If you meant 25º </span>
<span>A + (A + 25) = 90 </span>
<span>2A + 25 = 90 </span>
<span>2A = 65 </span>
<span>A = 32.5º </span>
<span>C = 57.5º</span>

Which equation represents the graphed function
xxMikexx [17]
It’s easy just find the slope and the answer is gonna be obvious

Slope= y2-y1/x2-x1

Slope = -2-(-1)/0-4 = -1/-4 = 1/4

Slope = 1/4x

So the answer should be C
