A line passing through the points (6.-2) and (-2, 4).
Complete the work shown:
1. Use slope formula to find the slope.
2. Substitute a point and slope in point-slope form.
3. Distribute the slope through the parentheses.
4. Solve for the y-variable.

I'm assuming that 9cm is the hypotenuse

of the triangle.

By using Pythagorean's theorem

a²+b²=c²

in this case, c =9

So, (x+5)² + (x-3)² =(x+5)(x+5) + (x-3)(x-3)

=x²+5x+5x+25+x²-3x-3x+9

=2x²+4x+31=81

And by solving the equation, you get two x values, but since you can't have x as a negative figure, the positive figure being 3.9498, x=3.95 (corrected to 3 significant

figures)

Step-by-step explanation:
