Answer:
The y-intercept of the line is the point (0,-41)
Step-by-step explanation:
we have the points
(-36,-117),(-27,-98) and (-18,-79)
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
take the points
(-27,-98) and (-18,-79)
substitute the values
step 2
Find the equation of the line in point slope form
we have
substitute
----> equation in point slope form
step 3
Convert the equation in slope intercept form
where
m is the slope
b is the y-coordinate of the y-intercept
isolate the variable y
therefore
The y-intercept of the line is the point (0,-41)
