What is the slope for (2, -1)(3,4)?

To find the slope, using the coordinates, you will plug them into the slope formula.

Slope formula:

You plug in the 2nd Y-cordinate in y2 and the 1st y-coordinate in y one. Then you do the same thing for the-x coordinates. Plug in the 2nd x-cordinate in x2, and 1st x-cordinate in x1.

You plug in 4 and -1 in the y2 and y1, respectively. Also, you plug in 3 and 2 in x2 and x1 respectively  

The equation you're going to get after plugging in is:

4-(-1) is the same as 4+1, so you add them. The subtract 3-2. Then you will end up with the fraction, further solving it will get you your answer.

The answer you will get is 5 after completing all of the steps with the slope formula.

The slope of the line is 5

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
