1. Write an equation for a line that has a slope of 4 and passes
through the point (-4, 7).

(y - 7) = 4(x + 4) or y = 4x + 23

Step-by-step explanation:

In point- slope form, the equation of a line is (y - y₁) = m(x - x₁)

The slope is given as 4, and so is point (x₁ , y₁). Substitute (-4, 7) as (x₁ , y₁), and do not forget to change the sign to a positive when you get a double negative.

(y - 7) = 4(x + 4) can further be expanded to slope- intercept form as y = 4x + 23

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
