B; if P equals one they would ha. have to divided it by 10 so do that to 4.3 and you would get 0.43
You multiply fractions simply by multiplying numerators and denominators with each other:

Y-y1= m(x-x1) point-slope form
y-0= -3(x-5)
solve this point-slope form to slope-intercept form. Use the information to graph the line.
