The slope, m, of a linear equation can be found using the formula m = StartFraction y 2 minus y a Over x 2 minus x 1 EndFraction
ExtremeBDS [4]

Answer: Third option.

Step-by-step explanation:

By definition, the slope of a line can be calculated with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

Since you need to solve for y_2 to find an equivalent expression, you can apply these steps:

1. You must multiply both sides of the equation by (x_2-x_1):

m(x_2-x_1})=(\frac{y_2-y_1}{x_2-x_1})(x_2-x_1})\\\\m(x_2-x_1})=y_2-y_1

2. Finally, you must add y_1 to both sides of the equation:

m(x_2-x_1})+y_1=y_2-y_1+y_1\\\\y_2=m(x_2-x_1})+y_1
