Answer:

Step-by-step explanation:

Pythagorean Theorem: a²+b²=c²

You can fill in the numbers you know: a²+4²=5²

(Hypotenuse must be side c)

Square those numbers and you have: a²+16=25

Subtract 16 from both sides: a²=9

Square root both sides and you get: a=3

Find the point below that lies on the line y-5=7(x-6).

MrMuchimi

Answer:

(6,5)

Step-by-step explanation:

The equation is in point slope form: $y-y_1=m(x-x_1)$

'm' is the slope.

(x1, y1) is the point used to create the equation.

The number 6 replaces the x1 spot.

The number 5 replaces the y1 spot.

So a point that lies on the line should be (6,5).
