equation for a line that passes through (0,-8) and (5,-8)

Answer 1

y =8 is the straight line that passes through the 2 given points

they both have the same y coordinate. that means slope = 0

y = (0)x + (-8) is express slope intercept form

or

y = -8

never hurts to plot the points and get a visual clue what's going on with a line through them

or calculate the slope,as the difference in y values over difference in x values. which = 0, then plug that into the linear equation y=mx+b where m= slope=0, and b= y intercept =-8 =the point (0,-8)
