They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula
.
Then, you can plug in one of the two points
or
into the formula y=mx+b to solve for b, which is your y-intercept.
If there are any rational roots, it would be a factor of your constant term (9) divided by a factor of the high-order coefficient (12).
Answer: A. intersecting
Step-by-step explanation:
1. To solve this problem and classify the system of equations shown above, you can graph it has you can see in the graph attached.
2. As you can see the lines intersect each other, this means that the system of equation has one solution and the lines are intersecting.
3. Therefore, the answer is the option A: Intersecting.
Answer:
y = 4
or (0, 4)
Step-by-step explanation:
intersecting the y-axis is basically when x is equal to 0.
1.5(0) +4.5y = 18
y = 4
So your y-intersect is (0, 4) and thats when it intersects the y-axis.
