7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?​
worty [1.4K]

Answer:

slope =-\frac{2}{3}

Step-by-step explanation:

Use the slope formula m = \frac{y_2-y_1}{x_2-x_1} to find the slope, or m. The x_1 and y_1 represent the x and y values of one point, and the x_2 and y_2 represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:

m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}

Thus, the slope is -\frac{2}{3}.

why do whole numbers raised to an exponent get greater while fractions raised to an exponent get smaller?
ehidna [41]
Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.
