Question

Find the slope of the line.

On a coordinate plane, a line goes through (0, negative 7) and (7, 0).
a.
Negative 7
c.
Negative 1
b.
7
d.
1

Answer 1

Given ↓

• Two points that a line goes through

To Find ↓

• The line's slope

Calculations ↓

When we have two points that a line passes through and asked to determine the slope of the line, the slope formula is going to come in handy.

This is the formula :

`\boxed{\\\begin{minipage}{3cm}slope~formula~: \\ $\displaystyle(y2-y1)/(x2-x1)$ \\ \end{minipage}}`

y2 and y1 are y-coordinates, and x2 and x1 are x coordinates

Plug in the values :

`\boxed{\\\begin{minipage}{3cm}$\displaystyle(0-(-7))/(7-0) $\end{minipage}}`

`\boxed{\\\begin{minipage}{3cm}$\displaystyle(0+7)/(7) \end{minipage}}`

Which simplifies to
`^7/_7`, or 1

Slope ↓
