Answer:
A) y=1/3x+5
B) y=-2x+9
C) y=-3
D) y=2x+9
E) y=-10x+80
F) y=x-2
Explanation:
Use y=mx+b
m=slope
b=starting point (or where it crosses the y-axis
For slope, use rise over run.
To determine negative slope, read from left to right and see if it’s going up or down. If down it’s negative, if up then positive.
Also BE CAREFUL, on D, the y-axis is labeled differently. Take an extra look at it.
Answer:
y = (x - 1) / 2 (First answer choice)
Step-by-step explanation:
1) Start with f(x) = 2x + 1
2) Replace f(x) with y: y = 2x + 1
3) Interchange x and y: x = 2y + 1
4) Solve this result for y: 2y = x - 1, or y = (x - 1) / 2 (This matches the first
answer choice.)

As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1
As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.
Given, a△b=a^2-b/b-a^2
now 4△3 = (4^2-3) / (3-4^2)
4△3 = (16-3) / (3-16)
4△3 = 13 / -13
4△3 = -1
Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.
- Mathematical operation: An operator in mathematics is often a mapping or function that transforms components of one space into elements of another.
