Answer:
Step-by-step explanation:Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).
Step 1: Find the slope of the line.
To find the slope of the line passing through these two points we need to use the slope
formula:
( )
( )
So the slope of the slope of the line passing through these two points is 3.
Step 2: Use the slope to find the y-intercept.
Now that we know the slope of the line is 3 we can plug the slope into the equation and
we get:
y = 3x + b
Next choose one of the two point to plug in for the values of x and y. It does not matter
which one of the two points you choose because you should get the same answer in either
case. I generally just choose the first point listed so I don’t have to worry about which
one I should choose.
(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.
–2 = –3 + b Solve for b and you will have the y-intercept.
b = 1
<span>In a survey in 2016, it was found that for 10 broad degree categories ranging from engineering to communications, projected average salary of a bachelor’s degree is </span><span>$50,556 in 2016. </span> In 2017, actual was $50,000 ($49,785, to be exact). If t$50,000 will be the basis, and the male who gets a job paying $ 40,760/yr, the difference in his yearly median income from obtaining a bachelor's degree is $9,240.

All you have to do is understand what fraction it is and reduce it. So first you have to figure out what the word reduce means and the word means another to figuring it out in its lowest terms and for example, your fraction 2/24 can be reduced in its simplest terms 1/12 and the way i did that was that i'd had to divide both the numerator and denominator by 2 because I know that both the numerator and denominator are divisible by 2 and so if you divide you get 1/16 and that's how you reduce fractions and so follow this procedure and you'll get everything correct.
