Answer:
The x-intercept is the point (22,0)
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
take the points
(-38,40) and (-23,30)
substitute the given values
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Find the x-intercept
Remember that the x-intercept is the value of x when the value of y is equal to zero
so
For y=0
solve for x
Multiply by 3 both sides
therefore
The x-intercept is the point (22,0)
