Whats the slope of (-3,4) (0, 0)
Maurinko [17]

Answer:

slope = -\frac{4}{3}  

Step-by-step explanation:

Use the slope formula, m = \frac{y_2-y_1}{x_2-x_1}, to find the slope. m represents the slope. x_1 and y_1 represent the x and y values of one point, and x_2 and y_2 represent the x and y values of another point. So, substitute the x and y values of the points (-3, 4) and (0, 0) into the formula appropriately and solve:

m= \frac{(0)-(4)}{(0)-(-3)} \\m = \frac{0-4}{0+3} \\m = \frac{-4}{3}

Thus, the slope is -\frac{4}{3}.
