Slope of the line that contains (-8,2) , (7,-4)

Nezavi [6.7K]

Answer:

$\mathsf{slope=-\dfrac25}$

Step-by-step explanation:

$\mathsf{let \ (x_1,y_1)=(-8,2)}$

$\mathsf{let \ (x_2,y_2)=(7,-4)}$

$\mathsf{slope=\dfrac{y_2-y_1}{x_2-x_1}}$

$\implies \mathsf{slope=\dfrac{-4-2}{7--8}=-\dfrac25}$

Find the equation of the line in slope-intercept form. m=− 4 7 through (14, 3

kakasveta [241]

Answer:

The answer to your question is: y = -47x + 661

Step-by-step explanation:

Data

m = - 47 I wasn't sure if the slope was -47 or -4.

Point (14, 3)

Formula

(y - y1) = m(x - x1)

Process

(y - 3) = -47(x - 14)

y - 3 = -47x + 658

y = -47x + 658 + 3

y = -47x + 661
