Y=9-x is slope-intercept form of that line, which means it has a slope of -1. Parallel lines have the same slope, so the slope of this new line will also be -1.

To find the line that goes through (5,1), we can use a blank equation y=mx+b. We know that m=-1, so we can use the given point to find b:

y=mx+b
Y=-x+b
1=-5+b
6=b

So the line would be y=-x+6.

An integer is chosen between 0 and 100. What is the probability that it is divisible by 7?
IgorC [24]
Assuming 0 and 100 are included in the possible choices:

There are \left\lfloor\dfrac{101}7\right\rfloor=14 multiples of 7 between 0 and 100, so there is a \dfrac{14}{101}\approx0.1386 probability of choosing a multiple of 7.
