Its all in the picture

The answer is -2x+5, or the 2nd choice.

Step-by-step explanation:

The graph is decreasing. This tells us that the function for slope must be negative. The second thing we should look at is the rise. For every unit forward, the vertical decrease is 2 units. This means the slope is -2, but we are not done yet. We can see that the y-intercept is 5. This is where the plus 5 comes in. In conclusion, we will end up with -2x+5.

Hope this helps!

B is the answer

Step-by-step explanation:

first find the slope all that takes is that you for this graph is go down 2 and right 1 from the point the line intersects the y axis and the slope is negative for this reason when ever you do rise over run down and left are negative and  up and right are positive so because you went down two points and right 1 point the slope is negative. therefore the slope is -2x. get it.

now the point where the line intersects the y axis is is called the y intercept therefore the y intercept is 5

so the equation that best represents the graph is y=-2x+5 so B is it
