Answer:
y = 20x + 5
Step-by-step explanation:
X = Y/20 - 1/4
In this type of expression you will first of all find the LCM of the right hand side
x = y - 5/ 20
the next thing to do is to cross multiply
we have,
20x = y - 5
dont forget we are to solve for y in the equation, so to solve for y we have
20x + 5 = y
therefore y will be expressed in terms of x as written below
y = 20x + 5

If you don't understand, I'll try to explain more :)
Answer:
[see below]
Step-by-step explanation:
Quadrant One has a positive value for both x and y. (+ , +)
Quadrant Two has a negative x value. (- , +)
Quadrant Three has a negative value for both x and y. (- , -)
Quadrant Four has a negative y value. (+, -)
Therefore:
(2, -3) would be plotted in Q4. It does not lie on any axis.
(0, 8) would be on the positive y-axis. (0 is neither negative nor positive.)
(-1, -2) would be plotted in Q3. It does not lie on any axis.
(4, 7) would be plotted in Q1. It does not lie on any axis.
9/50 is close to 10/50 or 1/5 or 0.2
7/15 is close to 7/14 or 1/2 or 0.5
0.2 + 0.5 = 0.7
0.7 is closer to 0.5 than 1
The answer would be B
