Question

What is the equation of a line that passes through the points -3,5 and has the slope of zero

Answer 1

All lines with zero slope is a horizontal line.

y=mx+c slope is m. If m were zero, any x value substituted in would make y=(0)x+c, y=c.

Sub in the values 5=(0)(-3)+c, c would then be 5. So the equation would be y=5.
