Step-by-step explanation:
since you have 11 cards and need to know how many red and black
r+b needs to equal 11
since r+b=11 isn't shown in any answer then none of them are correct, so none of the above
The easiest thing to find in a table showing a linear relationship is the slope. If the x is increasing by one each and every time (or cell because we are talking about tables), then the difference between each y value is the slope. Also, if you are lucky enough to have that sort of table, you can easily find the y-intercept by looking at the y value that is next to the x value of 0. Otherwise, work backward to find the y-intercept. For every x value you go down to try and get to 0, minus the y values also by the slope.
