Question

Graph y = 5x + 10 and explain how you found the points

Answer 1

The graph is a line and we want to see where it touches the x-axis and y-axis
If x=0 then y =5•0+10 =10 so
the point (0,10) belongs to the line
If y =0 then 5x+10=0; 5x=-10; x=-10/5=-2 so
the point (-2, 0) is also on the line
