Question

PLZ HELP ASAP!!!

please explain step by step explanation for below problems in comments after answer
1. solve equation for y: 3x - 4y = 16

2. what are the x- and y- intercepts of the line: 4x - 3y = -24

3. which ordered pair is on the graph of the equation 6x + 3y = 9

4. what is the slope of the line that passes through the points (4,8) and (1,6)​

Answer 1

1) y = 3/4x - 4

2) x-intercept: (-6,0) y-intercept: (0,8)

3) (-2,7)

4) slope: 2/3

Explanation:

1) subtract 3x from both sides, divide -4 from both sides, simplify right side which gives you y = 3/4x -4

2) to get x-inter: plug in 0 for y and solve for x, the equation should look like 4x = -24, divide both sides by 4 which gives you x = -6

get y-inter: plug in 0 for x and solve for y, the equation should look like -3y=-24, divide both sides by -3 which gives you y = 8

3) plug in the points from the choices and go from there

4) slope formula: m = y2-y1/x2-x1
