Let us start by graphing these points on a coordinate plane.(See picture) So, we can see that (-15,21) is in the 2nd quadrant. (4.5,10.6) is in the 1st quadrant. (-3/4,-4 1/9) is in the third quadrant.And finally, (3,-7) is in the 4th quadrant. Then we come to our y axis and the x axis. On the y axis we have (0,12)and on the x axis we have (18,0). Hope this helps!

Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth. 5x+2y=7

Rashid [163]

5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7

5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====
