Whenever you see <em>x </em> next to a 3, and it says that it equals 9, you know that 3•3=9.
Answer:
about 61 mph
Step-by-step explanation:
If the line is perpendicular, then as a rule the gradient of the perpendicular line will be the negative inverse of the gradient of the line given.
Therefore the gradient of the perpendicular line would be 1/2
so now just substitute in the equation of a line (y=mx+c) where y and x are given by -3 and 9, and your new m=1/2
