Answer:
y = .75x - 4.5
Step-by-step explanation:
y = mx + b
m = slope ; b = y-int
slope = rise/ run = 3/4 = .75
y = .75x + b
Because it is hard to determine the exact y-intercept, we plug in a point (2,-3):
-3 = .75(2) + b
-3 = 1.5 + b
-4.5 = b -->
y = .75x - 4.5
Answer:
16
Step-by-step explanation:
if ten dove int the water and 6 came back up there would be 4 left in the water.If there are now 12 penguins on the ice then there were 16 penguins to begin with.
Step-by-step explanation:
First you plot -4 on the y-axis at -4. Since the slope is -4x, you move your dot up 4 times than move it left once. Keep doing that until you think you have enough. Use a ruler to connect your points.
Same for #2.
This time Y is at positive 2 on the Y-axis. For this slope move y up once and than left once. Do it until you have enough dots than connect your dots in a straight line
