Whatis the answer to the problem
Stels [109]

Answer:

slope = -\frac{1}{8}

Step-by-step explanation:

Use the slope formula given in the question to solve for the slope. The m is the variable representing the slope. The x_1 and y_1 values are x and y values of one point. The x_2 and y_2  are x and y values of another point.

So, use the x and y values of the points given and substitute them in the correct order into the formula:

m = \frac{(7)-(9)}{(10)-(-6)}\\m = \frac{7-9}{10+6} \\m = \frac{-2}{16} \\m = -\frac{1}{8}

Thus, the slope is -\frac{1}{8}.

Y=1/4x−2y=−2x+3 help solve problem.
8_murik_8 [283]

Answer:

  (x, y) = (2 2/9, -1 4/9)

Step-by-step explanation:

Equate the values of y and solve for x.

  1/4x -2 = -2x +3

  (2 1/4)x = 5 . . . . . . . . add 2+2x to both sides

  x = 20/9 = 2 2/9 . . . multiply by 4/9

  y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation

  y = -1 4/9

The solution is x = 2 2/9, y = -1 4/9.
