Answer:

Step-by-step explanation:

slope (k) is the rise over run of the line

a way of finding the slope if you have two dots of the line is:

$k \: = \frac{y2 - y2}{x2 - x2}$

here the dots that belong to the line that you can most easily see are:

A(-6,0)

B(0,6)

by inserting the values into the euquation you get:

$\frac{6 - 0}{0 - ( - 6)} = \frac{6}{6} = 1$

good luck with your maths solving
