What is the slope of a line that is parallel to the line shown? (-3,2) and (0,-2)

Slope of a line which is parallel the line passes through (-3,2) and (0,-2) is

Solution:

Slope of the line which is passes through is

---- eqn 1

From question given that two points are (-3, 2), (0,-2). Hence we get  

By substituting the values in equation (1),

On simplifying above term,

If two lines are parallel then slope of both lines should be equal. That is slope of the line which passes through (-3,2) and (0,-2) is . so slope of a line which is parallel the line passes through (-3,2) and (0,-2) is also
