Question

What is the slope of 6x+10y=8

(choice A)
A -3/4

B -5/4

C -3/5

D -4/5

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 6x + 10y = 8 into this form by subtracting 6x from both sides

10y = - 6x + 8 ( divide all terms by 10 )

y = -
`(3)/(5)` x +
`(4)/(5)` ← in slope- intercept form

with slope m = -
`(3)/(5)` → C
