Question 173681: 1.what is the ordered pair to the solution of y= x-8

2. Determine the equation of the line, in slope-intercept form, that contains the points of (-5,9) and (-5,-2)

3. Convert 6.5432 mm^2 = ____cm^2

1. there are infinite solutions to y=x-8...this is an equation of a line....and all the points that make up that line are solutions. If you choose x to be 1 you plug it into the equation and solve for y. y=1-8=-7..so one ordered pair is (1,-7)....and this can go on forever.

2. we need to use the point slope formula to write this equation. In order to do this we need m the slope. m=change in y/change in x. Using our 2 points we have: -2-9/-5-(-5). The denominator is -5+5=0. Therefore this make the slope undefined. when a slope is undefined we know we have a vertical line and that line is parallel to the y axis and all x's equal -5 while y and be any value. the equation is written as x=-5

3.we know that 1cm=10mm6.5432+%28mm%5E2%29+%2A+%281%2F10%29%28cm%2Fmm%29
:
so 6.5432/10=.65432%28mm%29cross%28mm%5E2%29cm%2Fcross%28mm%29 our goal is mm%5E2so
:
we have 1 more step.
:
.65432+%28mm%29+%28cm%29+%2A+%281%2F10%29%28cm%2Fmm%29
:
.65432/10=highlight%28.065432%29 cross%28mm%29cm%5E2%2Fcross%28mm%29
:
1 sq centimeter = 100 square millimeters that is why we end up multiplying by
1/10 and 1/10 which = 1/100...the steps are to show how we get from mm%5E2 to cm%5E2
