Question

The y-intercept of the line whose equation is 3x + 2y = 7 A)-3/2 B)7/3 C)7/2

Answer 1

C

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 2y = 7 into this form

Subtract 3x from both sides

2y = - 3x + 7 ( divide all terms by 2 )

y = -
`(3)/(2)` x +
`(7)/(2)` ← in slope- intercept form

with y- intercept c =
`(7)/(2)` → C
