Use the slope formula below:
To form an equation of a line - we need to find a slope and the y-intercept from y = mx+b. We are given two points which we can substitute in the formula.
We have finally got the slope. Next is to find the y-intercept. First we rewrite the equation of y = mx+b by substituting the slope.
The equation above is the slope-intercept form. Substitute m = -7/6 in the equation.
Since the graph passes through (0,0) which is an origin point. In y = mx+b if the graph passes through origin point, that means the b-value is 0. Therefore:

-4 / 3 7 -20
-12 20
-------------------
3 -5 0
Because the remainder is 0, we know that -4 is a root and (x+4) is a factor. Note the new coefficients in the last row: 3 -5. They are the coeff. of the quotient, namely, 3x-5. So (3x-5) is a factor of the original polynomial.

Answer:
- 63 ft²
- h = 2A/b; h = 7 ft
Step-by-step explanation:
1. Put the values where the variables are in the formula, then do the arithmetic.
... A = (1/2)bh = (1/2)(18 ft)(7 ft) = 63 ft²
2. Divide by the coefficient of h. Substitute the given values and do the arithmetic.
... A = (1/2)bh
The coefficient of h is b/2, so we divide by that—or multiply by its inverse, 2/b.
... 2A/b = h
Substituting the given numbers, you have ...
... 2(28 ft²)/(8 ft) = h = 7 ft
The height of the triangle is 7 ft.
