What is the equation of a line with a slope of -2 that passes through the point (6,8)

Step-by-step explanation:

hello :

the point-slope formula is :  

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice :  x_1 = 6            y_1 = 8             m = -2  

so : y - 8 = -2(x - 6)   ...an equation for this line .

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

i think the answer is 90 hope this
