Which choice represents the equation for the line of best fit for the data shown in the table and graph?

Answer: d y = x + 12.14

explanation:
the first point starts above 10 on the y axis so it should have a y intercept higher than 10.
right away, you can eliminate choice b because it has no y intercept.

the next step is find the slope of two points.
slope is change y over change in x
for the first two points:
=> (15-3)/(13-1
=> 12/12 = 1

for the next two points
=> (18-9)/(14-5)
=> 9/9 = 1

so your slope is 1. choice d has a slope of 1. you can also see that choice c is unrealistic before doing this because it’s slope is 12, which is super high.

D

Step-by-step explanation:

So we are given a line and are asked to find the equation for the line. To do this we need 2 things: the slope and a point on the line (preferable the y-intercept). Remember, the equation for a line in y-intercept form is:

y = mx + b

Where m is the slope and b is the y-intercept.

From looking at the image, we can see that the line intercepts the y-axis at y = 0. Thus, the y-intercept is 0. So our equation for the line becomes:

y = mx

Where m is the slope. Now we must find the slope in order to find the equation for the line. Remember:

Notice how the y-value of the line decreases by 1 when the x-value increases by 4. This means that we can use the -1 for the rise (or the change in y) and 4 for the run (or the change in x). Plugging in we get:

Thus, our slope would be -1/4. Plugging into our equation for the line we get:

Thus, our equation would be .

Our answer would be D .
