Given the scatter plot, choose the function that best fits the data. scatter plot with data points that form an upward curve staring at the origin and continuing to the right

f(x) = 2x
f(x) = 2x
f(x) = −2x
f(x) = 2x2

I’m pretty sure the slope would be 1 since the x and y values increase by 1

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
