Question

What is the equation of the line that passes through the points (7, 0) and ( - 5, 4)?

Answer 1

Start by solving for the slope using y2-y1/x2-x1
4-0/-5-7
4/-12
Or -1/3
Y=MX+b
Y=-1/3x+b
Sub in one of the points for x and y to solve for b
4=-1/3(-5)+b
4=5/3+b
4-5/3=b
B=7/3
Therefore the equation is y=-1/3x+7/3
Hope this helps!
