Answer:

y = 3x -2

Step-by-step explanation:

General equation of a line in the slope intercept form is

y = mx + b ,

where m is the slope and b is the y-intercept ( where intercepts the y-axis)

y = 3x + b ,

because is given slope is m = 3

For point (x = -2, y = -8) we have

-8 = 3 (-2) + b

-8 = -6 + b

-8 + 6 = b

-2 = b

The equation of the line that passes through the point (-2,-8) and has a slope of 3 is

y = 3x -2

Which situation CANNOT be represented by this equation? -5x +170=125
Helen [10]

It is A because she can not have 125 in her account at the beggining of the month and end with 170 at the end of the month if she spends money.

B and C all make logical sense of her bank account decreasing over the month.
