You solve for y
4y=-6x+2
y=-6/4x+2
y=-2/3x+2
Slope is -2/3, the number in front of x is the slope.
To find the mean (average), we first need to add up all the test scores (14 + 19 + 19 + 20 + 16 + 18 + 15 + 17 + 12 = 150). Then, we need to divide that number (150) by the number of numbers in the data set (9 in this case). So the mean of these test scores is about 16.6666666667.
53.67 to one decimal place is 53.7 since you round the .6 to the .7
