Question

Y = mx + b is the slope-intercept form of a linear equation where m = slope and b = y-intercept.

Ax + By = C is the standard form of a linear equation.
Which expression gives the y-intercept of the line when the equation is in standard form?



A.-c/b
b.c/-b
c.c/a
d.c/b

Answer 1

C/B

Explanation:

Ax + By = C

Subtract Ax from each side

Ax -Ax+ By =-Ax+ C

By = -Ax +C

Divide each side by B

By/B = -A/Bx +C/B

y = -A/Bx +C/B

The y intercept is C/B
