Question

what is the equation formula when a straight line goes through -8 on the x-axis and 2 on the y axis and ends on the positive 8 on the x axis?

Answer 1

Hi there,

when a line goes thru -8 on the x-axis [also called x-intercept], it means that y=0, so you have 1 point (-8,0).
when a line goes thru 2 on the y-axis [also called y intercept], it mean that x=0, so you have another point (2,0)

Do you have formula for line equation with 2 points?
