Please Help need this ASAP A line of best fit goes through the points (5, 21) and (11, 3). What is the equation of this line of best fit?

y=-3x+36

Step-by-step explanation:

Y=Mx+b

m= change in y/change in x

21-3/5-11= 18/-6=-3

y=-3x+b

we can substitute x and y

21=-3(5)+b

21=b-15

b=36

y=-3x+36

Step-by-step explanation:

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
