Question: `q001YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
X Y Y=2x+7
-3 1 Y = 2 (-3)+7= -6+7 = 1
-2 3 Y= 2(-2) + 7 = -4+7 = 3
-1 5 Y= 2(-1) + 7 = -2+7= 5
1 9 Y= 2(1) + 7= 2 +7 = 9
2 11 Y= 2(2) + 7= 4 + 7 = 11
3 13 Y=2(3) +7= 6+7 = 13
X Y Y=3x-4
-3 -13 Y= 3(-3) - 4 = -9 - 4 = -13
-2 -10 Y= 3(-2) - 4= -6 - 4= -10
-1 -7 Y= 3(-1) - 4= -3 - 4= -7
1 -1 Y= 3(1) - 4= 3 - 4 = -1
2 -2 Y= 3(2) - 4= 6 - 4 = -2
3 -5 Y= 3(3) - 4= 9 - 4= -5
X intercept: Y Intercept:
0=3x-4 y=3(0)-4
4= 3x y= 0-4
4/3=3x/3 y= -4
X= 4/3
