Multiply both by -1: 113.75-112=1.75
multiply answer by -1: -1.75
The slope of the given line is -2, and since perpendicular lines have negative reciprocal slopes, the slope of the line we want to find is 1/2.
Substituting into point-slope form,

The answer is 1
factors of 25 are 25, 5, 1
factors for 77 are 77, 11, 7, 1
Hey there! :)
Your answer is: Between 11 and 12
11² = 11 × 11 = 121
12² = 12 × 12 = 144
129 is between 121 and 144
Hope this helps :)
