found that 11% of the students had both a pet dog and a pet cat.
What is the probability that a randomly chosen student at Michael's school will have a pet dog or a pet cat?
Y=-3x+4 Gradient, m= -3 Parallel lines have equal gradients; So, equation II, y=mx+c y=-3x+c Replacing for x and y using point (-4, 6) 6=-3(-4)+c 6=12+c 6-12=c c=-6 y=-3x-6
