Write the slope-intercept form of the equation of each line (show work)

1. -5/3x+4

2. -7x+2

3. -2/5x-4

Step-by-step explanation:

The way you calculate slope is rise over run. This will determine your x. Your y-intercept is determined by the point the y-intercept connects with. So if the line crosses (0,-4), the -4 is the whole y-intercept. If that makes sense?

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
