I need help with this question?

Directions:Write the equation of each line. Explain what the slope and y-intercept represents in the context of each graph.

Answer 1

the y intercept is where the line passes through the y axis so y=0
we are gone find 2 points on the graph so i would use (10,30) (20,60)
m=y2-y1/x2-x1
60-30/20-10
30/10
m=3
slope = 3
equation is y=3x
