Select the equation of the graphed line above. Question 2 options: A) y = 3x + 5 B) y = 3x – 5 C) y = x + 5 D) y = x – 5

Explanation:

The y intercept is -5 as this is where the diagonal line crosses the vertical y axis. The answer is between B and D as these choices have a y intercept of -5.

The y intercept is located at (0,-5). To get to the next point over, we move 3 units up and 1 unit to the right to get to (1,-2). This line goes through (0,-5) and (1,-2). You can use the slope formula with those two points, or any two points on this line, to find that the slope is 3.

m = 3 is the slope, b = -5 is the y intercept

y = mx+b turns into y = 3x+(-5) or simply y = 3x-5

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
