2 is true since the absolute value of -6 is 6 and the absolute value of -8 is 8. The absolute value of a number will always be the number itself but positive. Also 6 is less than five which make this true.
The given line goes up 3 units for every 1 unit it goes to the right, so its slope is 3. If it is made to go through point (2, 1), it will be moved 2 units to the right. This means the y-intercept will be below its current value of 1. The only appropriate choice is ...
... C y = 3x - 5
10*3 = 30 (three rows of fences)
30*1.75 = $52.5
Hope this helps! :)
The line x=4 is a straight vertical line. If we were to measure it's slope using rise over run, we will get 0 in the denominator because there is no change in the x direction. Therefore, the slope of the line is undefined.
