Answer:

y= -0.2x+14

Step-by-step explanation:

you have to do y2-y1/x2-x1 of any two coordinates or points so you could do 9.8-10.2/21-19 then you get -0.4/2 and that equals -0.2 so -0.2 is now ur slope or M. Next you pick any coordinate like (19,10.2) and you plug that into ur y=mx+b to find the b since you have found the m already from y2-y1/x2-x1. You could do 10.2= 19(-0.2)+b once you do the algebra to solve this you get 14 as your b or y intercept

Answer:

equation of the line is y=x+1

Step-by-step explanation:

the equation of a line has the form y = mx + b

while m is for the slope and b is for the y-intercept.

you can see from the graph that the line intercepts the y-axis at y=1 this is the b.

you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:

<h2>m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }</h2>

in our case it will be:

m=\frac{4-2}{3-1} = \frac{2}{2}=1

then just substitute the values for m and b.

sergij07 [2.7K]

Answer: The MAD describes the average distance from a data point to the mean. It measures variability. For this data, it shows that Evelyn’s scores varied slightly more than Robin’s.

Step-by-step explanation: Add 8+1+5+0+12 and divide it by 5 and get 5.2

You are ordering a pizza and soda for the big game. A deep dish pizza costs $10.25, and a two-liter of soda is $2.00. For each t
lions [1.4K]
10.25 + 2.00 = 12.25...cost of pizza and soda

12.25 - 1.50x = 4.75....with x being the number of touchdowns
-1.50x = 4.75 - 12.25...I subtracted 12.25 from both sides
-1.50x = - 7.50...now divide both sides by -1.50
x = -7.50 / -1.50
x = 6......They would have to score 6 touchdowns
