write equations for the horizontal and vertical lines passing through the point (4, -6)

So you have the vertical line passing through is x=4 and the horizontal line passing through is y=-6.

Step-by-step explanation:

In general the horizontal line passing through (a,b) is y=b and the vertical line passing through (a,b) is x=a.

So you have the vertical line passing through is x=4 and the horizontal line passing through is y=-6.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
