Question

Find the slope of the line

A) 4

B) 1

C) -1

D) -4

Answer 1

D) -4

Explanation:

`\bold{METHOD\ 1:}\\\\\text{look at the picture}\ \#1\\\\\text{The fomula of a slope:}\\\\m=(y_2-y_1)/(x_2-x_1)\\\\\text{Form the graph wi hate points:}\\\\(-1, 3)\ \text{and}\ (0, -1).\\\\\text{Substitute:}\\\\m=(-1-3)/(0-(-1))=(-4)/(1)=-4`

`\bold{METHOD\ 2:}\\\\\text{look at the picture}\ \#2\\\\slope=(rise)/(run)\\\\rise=-4\\run=1\\\\slope=(-4)/(1)=-4`

Answer 2

(-1,3), (0,-1)

(-1-3)/(0+1)= -4/1= -4

the answer is d
