Help but explain good how to solve this question

The line has a slope of -7/6

Step-by-step explanation:

To find the slope of a line, you only need two of its points.  Slope is defined as the difference along the y axis divided by the difference along the x axis.

So let's take any two points, and find that slope.  We'll use (-8, 8) and (-2, 1):

So the slope of the line -7/6

answer: c i think

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
