5 A line with a y-intercept of -2 contains the
point (-3, -7). Which equation describes
the line?
A 5x + 3y = 6
B 5x – 3y = 6
-
C
3x + y = 2
D 3x - y = 2

Answer 1

B

Explanation:

First off, the equations are in standard form, not slope-intercept form.

• Formula ⇒ Ax + By = C

To find the y and x intercepts, divide by the total number (number to the right of the equal sign) by the coefficients next to the variables.

The y represents the y-axis / y -intercept. So 6 / 3 = 2 ( This is to find the y-intercept given, (OPTION 1 )).

Option 1 can be eliminated.

For the next one, 6 divided by -3 = -2. The y-intercept is the result of dividing the total by the coefficient by the y. So since we got the given y-intercept the option that is correct is B.
