The slope-intercept form:
m - slope
b - y-intercept
<em>subtract x from both sides</em>
<em>change the signs</em>
It's a linear function.
We need only two points to plotting a graph.
We choose any three values of x and calculate y.

Answer: approximately <u>188.07</u> feet
======================================================
Explanation:
Refer to the diagram below. Note that the 62 degree angle is from the fact that 90-28 = 62.
With the reference angle 62 degrees in mind, we have an unknown opposite side x feet and a known adjacent side 100 feet.
Use the tangent trig ratio to tie the two sides together, and then solve for x.
tan(angle) = opposite/adjacent
tan(62) = x/100
100*tan(62) = x
x = 100*tan(62)
x = 188.072646534633 approximately
x = 188.07 feet approximately
Your calculator needs to be in degree mode. One way to check is to compute something like tan(45) and the result should be 1.
<u>Answer:</u>
The correct answer option is C. pounds
<u>Step-by-step explanation:</u>
We are given that Emma has pounds of potato salad and
pounds of egg salad for a picnic.
We are to find out how much more pounds Emma has of potato salad than the egg salad.
