Y = 7x + 50. Use slope-intercept form (y = mx + b), where m is slope, and b is the y-intercept. Insert the values we already know into the equation. y = 7x + b. Now, insert the x and y-values of your order pair into the equation and solve for b. 8 = 7(-6) + b ---> 8 = -42 + b --> 8 + 42 = -42 + b + 42 --> 50 = b or b = 50. Now that we have the value of b, insert it into the equation as well, and then you have your answer. Answer: y = 7x + 50

Y-y1=m(x-x1)
y-8=7(x-(-6))
y-8=7(x+6)
y-8=7x+42
  +8      +8
y=7x+50

There are 52 weeks in one year. If we divide 159 by 52 we get 3.05. Therefore, there would be an average of 3-4 murders per week.
