What is the slope of the line that passes through the points (-5 8) and (-9 16)

Work Shown:

The two points are

(x1,y1) = (-5, 8) and (x2,y2) = (-9,16)

Use them in the slope formula

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

m = (16 - 8)/(-9 - (-5))

m = (16 - 8)/(-9 + 5)

m = (8)/(-4)

m = -2

The slope is -2. This is equivalent to the fraction -2/1.

Extra info:

slope = rise/run

slope = -2/1

rise/run = -2/1

rise = -2 and run = 1

A negative rise means you go down 2 units.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
