Question

For the function whose graph is shown, which is the correct formula for the function?

Answer 1

Answer:

d

Step-by-step explanation:

Try using simple numbers like 1 as x and then try with the different functions until it works

Answer 2

Answer:

y=-2x+3

Step-by-step explanation:

Here we are given a graph of line. We can see from the graph that the y intercept . i.e the distance of the the point at which it intersect y axis from (0,0) is 3.

Also we see that the line is making obtuse angle with the positive x axis . Hence tan of this angle will be negative or we can say that the slope of this line is negative

Now the equations in options are given in slope intercepts form

y=mx+c

where m is slope and c is y intercept

Hence in the given four options we see that only 3rd and 4th option has y intercept as 3

But the slope of 3rd is positive and that of 4th is negative . Hence our answer is 4th option
