Answer:
Graph the point (1, -4), then proceed to use the slope either way. for example another point would be (-2, -5)
Explanation: As the least common multiple of two numbers is 60 , the two numbers are factors of 60 . Among {1,2,3,4,5,6,10,12,15,20,30,60} ,5 & 12 is the only two pair of numbers whose difference is 7 .
Answer: 5 & 12
THE EQUATION TO THIS PROBLEM IS y=2x+12
the answer for the second problem is x=99 degrees and y= 261 degrees
dunno the first problem :/
