● To do this, you need to multiply 6.75 by 21 to find out how many meters are in all. 6.75×21 is 141.75
● Next you multiply 141.75 by 2 to see how much it costs which is 283.5
● Since we're dealing with money, it would have two place values so we add a zero and we get $283.50
Plot the y-intercept (0,-1) and then from that point go up seven and to the right one. Plot that point, then draw the line between the two points.
Hope this helped! Good luck! :)
Your answer would be y + 9 = m(x + 6)
The answer for this will be
-1/3x+3
