Find y please show work thank you

y=4

Step-by-step explanation:

This is a 45-45-90 triangle. It is also a special triangle. The hypotenuse is x√2. X is sommon through all 3 sides. The legs of the triangle are x in length each.

Looking at the picture, we see the hypotenuse is equal to 4√2. We can set this equal to the hypotenuse to find what x is.

4√2=x√2

x=4

Since we know that the legs of the triangle are both equal to x, we knoe that y=4.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
