Which of the following equations is of a line whose slope is 3/4 and y-intercept is 6?
a.3x-4y=-6
b.3x-4y=6
c.3x-4y=-24

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

here m = and c = 6, hence

y = x + 6 ← in slope- intercept form

multiply through by 4

4y = 3x + 24 ( subtract 4y from both sides )

0 = 3x - 4y + 24 ( subtract 24 from both sides )

- 24 = 3x - 4y , that is

3x - 4y = - 24 ← in standard form

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
