Question

What is the slope of a line with the points (3.8, -4.7) and (6.2, 2.9)?

A. Zero

B. Positive

C. Undefined

D. Negative

Answer 1

Slope formula:
y2 - y1 over x2 - x1

Answer 2

2.9 + 4.7 over 6.2 - 3.8

Answer 3

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 3.8}}\quad ,&{\color{blue}{ -4.7}})\quad &({\color{red}{ 6.2}}\quad ,&{\color{blue}{ 2.9}})
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

Answer 4

How do I do that? Someone told me that before and he was told not to help me so he never got to explain
