The correct answer is -3/4, or option B.
Between these two points, the y value has gone down by 3, and the x value has changed by 4.
Since we know slope is rise/run, this means that the slope is -3/4
It would depend on what n was equal to
40 degrees - 32 degrees = 8 degrees
8 degrees divided by 1.8 = 4.4444444 degrees
to divide add a decimal point and zero to the 8 and move the decimal point 1 place to the right in 1.8 and in 8.0 and divide from there
x = 3 is a vertical line that goes straight up and down at 3 on the x axis, vertical lines have a undefined slope. Don't confuse that with no slope which is a flat like like y=7.
so the slope is undefined
