Wendy gets a new job and receives a $800 bonus then she makes $250 a day. What is the y-intercept?
we know that
The equation of the line in slope intercept form is equal to
y=mx+b
where
m is the slope
b is the y-intercept or initial value
In this problem
m=250
b=800
therefore
the y-intercept is (0,800) or simply $800
Part 2
Write the equation for the line in slope-intercept form: Slope is 6, and (3, 1) is on the line.
we know that
The equation of the line in slope intercept form is equal to
y=mx+b
where
m is the slope
b is the y-intercept or initial value
substitute the given values
we have
m=6
(x,y)=(3,1)
substitute
1-(6)(3)+b
1=18+b
solve for b
b=-17
therefore
y=6x-17
