If (-3,-4) is a point on the line y =mx+2 ,find the value of m

m = 2

Step-by-step explanation:

Given

y = mx + 2

Since (- 3, - 4) is a point on the line then it satisfies the equation.

Substitute x = - 3 and y = - 4, the coordinates of the point, into the equation and solve for m, that is

- 4 = - 3m + 2 ( subtract 2 from both sides )

- 6 = - 3m ( divide both sides by - 3 )

2 = m

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
