the slope of a graphed line is -9 and the y-intercept is (0, -2). what is the
slope-intercept equation of the line?
o a. y = -9x-2
o b. y=-2x - 9
o c. y=9x-2
o d. y = 2x+ 9

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept (0, b)

We have the slope m = -9 and the y-intercept (0, -2) → b = -2.

Substitute:

y = -9x + (-2) = -9x - 2

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

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.
