Answer:
D. 21/26
Step-by-step explanation:
Slope (m) = y2-y1/x2-x1
Input coordinates into formula:
m=5-(-16)/18-(-8)
m=21/26
Answer:
21/26
Step-by-step explanation:
we must use the formula y2-y1/x2-x1, this is the formula used to find the slope when given two points
-we are given two points, so we mark each point as y2,y1,x2, and x1
-for the first point given, we mark -8 as x1, for it is our first x value, and we mark -16 as y1, for it is our first y value
-for the second point, we mark 18 as x2, for it is our second x value, and we mark 5 as y2, for it is our second y value
-by plugging those numbers into our equation, (y2-y1/ x2-x1) we get 5- (-16)/18- (-8)
-we get 21/26
