Answer: A sum
Step-by-step explanation: The result of adding two or more numbers together is a sum.
Multiples of 30 : 30,60,90,120,150....
and the first one that 4 goes into evenly is 60
Slope is rise over run or Y2 - Y1 divided X2 - X1. The X's and Y's are your coordinate points. It doesn't matter which Y you put down first but remember to choose the X in the same place. Your coordinate points are (0, -1) and (-4, 2)
Your equation will be:
-1 - 2 / 0 - (-4)
-3 / 0 + 4
-3 / 4
Your slope is negative 3/4
