Answer: Here are all of the answers to the best of my ability :)
1: Solve the following equation for “y”:
3y - 4x = 15
Steps:
1. Add 4x to both sides. 3y = 4x + 15
2. Divide both sides by 3. Y= 4/3x + 5
Final answer: y= 4/3x + 5

2. Write an equation in slope intercept form for a line that passes through the y axis at 5 and has a slope of -3.
Slope intercept form: y = mx + b
B= y intercept
Mx= slope
Equation: y = 3x + 5

3. Is (-2, 6) a solution of -3y + 5y = 4x?
Steps:
1. -3(6) + 5(6) = 4x
2. -18y + 30y = 4x
3. 12 = 4x
4. Rewrite the equation: 4x = 12
5. Divide by 4 on both sides
6. x = 3
Yes, this is a solution to -3y + 5y = 4x

4. Write the following equation in slope intercept form: x + 8y = 30
1. Add negative 8y to both sides. X = -8y + 30
Answer: x= -8y + 30
——————————————————————————-
5. Graph this equation: 2x + 5y = 20
That’s all I could find. Sorry if I made I mistake. Have a good day!

First, lets break up the equation into pieces.
The first variable is slope, in your case here, we have a slope of -3 or -3/1.
The other variable is the y-intercept, which is where place on the graph where you plot (0,X), in your case here we got (0,-4). That is the y-intercept.
to graph it you have to plot the y-intercept, and then identify the slope.
Here is an example.
