Answer:
y = 2x+8
Step-by-Step Explanation:
The equation should be in the form of y=mx+b
So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8

Answer:
1. x = 12
2. x = 5
Step-by-step explanation:
1. -222 = -2x - 12x - 54
-222 = -14x - 54
-168 = -14x
x = 12
2. 154 = 2x + 12x + 84
154 = 14x + 84
70 = 14x
x = 5
