The formula for area of triangle is -

________________________________
So, the area of first triangle =



________________________________
Area of second triangle =



________________________________
Area of second triangle - Area of first triangle



For this problem, I'd use cross-multiplication.
9/12 = x/8.
When cross multiplying, multiply 12*x and 9*8. This leads to a new equation:
12x = 72.
Then you solve as an algebra problem.
*Divide 12 on both sides*
x = 6.
The y-intercept is (0,2)… Hope this helps..
