My explanation is attached below.
Step-by-step explanation:
In the picture.
The answer is <em><u>X = 61°</u></em>
Point A, because the square root of 81 is 9, and 83 is just slightly larger than 81. Point A is slightly more than 9, and all of the other points are out of range, so the answer is A
(60,4)(120,8)
slope = (8 - 4) / (120 - 60) = 4/60 = 1/15 <== the constant of proportionality is the slope
Well make the equation into slope intercept form: y=mx + b and whatever the coefficent is to x will be your slope
8x+2y= 5 can be written as y= (-8/2)x + (5/2) so the slope would be (-8/2)
