Question 485308
y=3/7x-1, find the y coordinates of the points (-7),(0), (7) plot those points

x=-7 y= 3/7 *-7 -1 = -4 (-7,-4)
x=0,y=-1 (0,-1)
x=7,y=2) (7,2)

Plot the points and draw the line graph

{{{drawing(500,500,-10,10,-10,10,circle(-7,-4,0.3),circle(0,-1,0.3),circle(7,2,0.3),graph(500,500,-10,10,-10,10,y=(3x/7)-1))}}}
