You need to understand Rise over Run (r/r) to find these equations.
Rise over run works by counting how far a point on the line is from another.
You do this by first counting how much higher or lower a point is from another then how far it is from the left or right side.
So to answer the equation for #2,
Your Rise over Run is: 3/4
Which translates to Y = 4x + 3
Finding line #1 is actually much easier. All you need to know is how far up it is, which is 8 units
So that’s just Y = 8
Finding a slope parcel to the 2nd line is a lot easier than you might think.
We know the slope of line #2 is Y = 4x + 3.
Parallel means if two lines were next to each other and kept going, they won’t intercept. Like the equals sign, =.
So to find a parallel line, you can just add or subtract the same number from Y to X
Y = 4x + 3
4x + 2 = 6x
3 + 2 = 5
=
Y = 6x + 5
