Answer: All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
The answer is C because there is an open circle(not including the number it's on) on the 60 mark and the arrow goes to the left, or to the lower numbers.

Determine f(-1); f(0) and f(2)
Solving f(-1)
In this case, we simply take x as;
Substitute -1 for x in
Apply law of indices
Solving f(0)
In this case, we simply take x as;
Substitute 0 for x in
Solving f(2)
In this case, we simply take x as;
Substitute 2 for x in
Emma’s average speed in kph should be 54 kilometers per hour. I got this by putting 1 hour and 20 minutes into just minutes. which would be 80 minutes then dividing 72km by 80 minutes. Which gave me 0.9. Then multiplying 0.9 by 60 because there are 60 minutes in an hour. Which gave me 54 kph. hope I helped.
The distance between the two points will be given by:
d=√[(x-x1)^2+(y-y1)^2]
point z1=(3-2i) has the coordinates of (3,-2)
point z2=(5-8i) has the coordinates of (5,-8)
thus the distance between them will be:
d=√[(-8-(-2)²+(5-3)²)]
d=√[(-6)²+2²]
d=√(36+4)
d=√40
d=2√10
