Question

What is the slope of this line? (-8,6) (-2,0) (0,-2

Answer 1

Hello there,

The points given: (-8,6) (-2,0)

y-intercept is: (0,-2)

Slope intercept form: y = mx + b

Slope: y2-y1/x2-x1

0-6/-2-(-8) = -6/6

Answer: -1

Hope I Helped!

Answer 2

Slope is -1

Explanation:

We have that the equation of a line is:

y = m + bx

where, m is the slope, but to know the slope we have a formula that is:

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

We have 3 points of the line:

(-8,6); (-2,0); (0,-2)

When we want to know the slope we need two points and they can be any two points in any order, so we can say we are going to use:

Point 1:

(-8,6)

Point 2:

(-2,0)

y1 = 6; y2 = 0

x1 = -8; x2 = -2

Now we substitute the values in the formula for m:

m = (0-6) / (-2+8)

Now we solve:

m = -6/6

m = -1, This is the slope.
