To find slope of two points connected by a line, you have to use the formula

divided by

. Do six minus one or one minus six and find the absolute value (5). Now divide that by -4-(-5) or -5-(-4) and find the absolute value (1). 5/1. The slope is five.

Factor

answer is 3 and -1
Answer:
13
Step-by-step explanation:
square root y^2 = square root 169
so
y = 13
The least common multiple (LCM) to determine the least common denominator for 2/3, 5/6, and 9/4 = 12.
