What is an equation of the line that passes through the points (-8, 2) and (-4, -3)?
denpristay [2]

Answer:

y = (-6/13)x + (4/13).,

Step-by-step explanation:

the equation of the line is:

y = mx + b, where "m" is the slope and "b" gives the y-intercept

m = (y2 - y1)/(x2 - x1)

m = (-2 - 4)/(5 - (-8))

m = -6/13

y = (-6/13)x + b

the line passes through the point (-8,4) means that for x = -8, y = 4

4 = (-6/13)(-8) + b

b = 4 - (-6/13)(-8)

b = 4/13

the equation of the line that passes through the points (-8,4) and (5,-2) is:

y = (-6/13)x + (4/13).

Find the slope in (-2,8) and (1,6)
Salsk061 [2.6K]

Formula for slope: \frac{y2 - y1}{x2 - x1}

y₂: 6

y₁: 8

x₂: 1

x₁: -2

Plug them into the slope equation:

\frac{6 - 8}{1 - (-2)}

--> \frac{-2}{1 + 2}

---> -\frac{2}{3}

The slope is -\frac{2}{3}.
