Plot all points on the coordinate plane and combine these points by lines to get triangle ABC (see attached picture for details).
Write the equation of side AB:
To find y-intercept you have to substitute x=0, then:
The point is the point where line AB intersects y-axis.
Answer:
Step-by-step explanation:
we have
Solve for x
That means ----> Isolated the variable x
Adds the constant term 5 both sides
----> variable terms isolated on one side and the constant terms isolated on the other side
Combine like terms
Divide by 3 both sides
