Answer:

hypotenuse = 10

Step-by-step explanation:

If you can tell at first glance it is a 3,4,5 triangle (6,8,10)/2=(3,4,5). Then you know that c has to equal 5.

If not,

a^2+b^2=c^2

6^2+8^2=c^2

36+64=c^2

100=c^2

10=c

1. **What is the slope of a line that passes through the points (-1,30) and (4, 10)

tresset_1 [31]

Answer:

Slope = -4

Step-by-step explanation:

Given points are :

(-1,30) and (4, 10)

We need to find the slope of the line that passes through these points.

We know that, the formula for the slope of line is given by :

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10

Put values in the above formula.

$m=\dfrac{10-30}{4-(-1)}\\\\=\dfrac{-20}{5}\\\\=-4$

So, the slope of the line is -4.
