What is the slope of a line that is parallel to the line y= -12

Parallel lines have the same slope.

y = -12 has the slope m = 0.

Therefore, a line parallel to y = -12 has the slope m = 0.

The slope-intercept form: y = mx + b

m - slope, b - y-intercept

y = -12 = 0x - 12

m = 0, b = -12

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.
