This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.
It says that the value of a box above two boxes is found by adding the expressions in the two boxes. I filled in the boxes. The top box is 13x + 30, or option B.
The probability of spinning a prime number and not flipping heads will be given as follows: P(Prime)*P(Tails) P(Prime)=3/5 P(Tails)=1/2 Thus P(Prime) and P(Tails) =3/5×1/2 =3/10
