If you distribute -5 to the things in the parenthesis you would get 10k-20 which is the same as -5(-2k+4)
Estimated probability=number of outcomes in question/divided by total number of trials
ep=102/300
ep=51/150 (34%)
Step-by-step explanation:
first step is to find the gradient of the line which "m" on the equation
gradient formula is y2 - y1 ÷ x2 - x1 = -½ as shown on the picture we substituted those points given
2nd step is to substitute on the equation y=mx+c
m= -½
y= 3 (you can choose any from those given points but in my case I chose point A)
x= -2
c= ? only unknown variable so we can can calculate it
substitute as shown on the picture to get c= 2
therefore our equation of the line will be y= -½x+2
