Algebra 2 What is the equation of a line with slope -2/7 and intercept (0, -1)?

A) y = -2/7x

B) x = -2/7y - 1

C) y = -1

D) y = -2/7x - 1

Please show work so I can understand.

D

Step-by-step explanation:

Recall the slope-intercept form of a line:

y = mx + b

slope -2/7 means m = -2/7

y = -2/7x + b

Intercept at (0, -1)

x = 0 and y = -1.

Hence, let's plug it back into the equation we made earlier (y = -2/7x + b)

(-1) = -2/7(0) + b

-1 = b

b must be -1

y = -2/7x -1

55? i think maybe

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
