Question

What is the y-intercept of the function, represented by the table of values below?
x=(-2,1,2,4,7)
y=(15,6,3,-3,-12)

Answer 1

help plz

Answer 2

Pick any two points from the table. Find the slope of the line connecting those two points. substitute your slope (m) into the slope-intercept form of the equation of a straight line:

y=mx+b.

Substitute the coordinates of any of these points into y=mx+b.

Solve the resulting equation for b.

Done.
