Find the slope of a line that passes through the points (3, -5) and (-7,5)

Mathematics
1 answer:
STatiana [176]3 years ago
4 0

Answer:

Slope = -1

Step-by-step explanation:

(3, -5 ) = (x_1,y_1) \\  (-7,5)=(x_2,y_2)

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

Substitute values into the given equation

slope \:  =  \frac{5 - ( - 5)}{ - 7 - 3}  \\  \\ slope \:  =  \frac{5 + 5}{ - 7 - 3} \\ \\

slope \:  = \frac{10}{ - 10}    \\ slope \:  =  - 1

What is the equation in point-slope form of a line that passes through the points (-4, -1) and (5, 7)?
Setler [38]

Answer:

y + 1 = 8/9(x +4)

Step-by-step explanation:

Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9

Using (-4, -1)

y-(-1) = 8/9[x- (-4)]

y + 1 = 8/9(x +4)
