What is the equation of the line shown in this graph? <br><br>any links will be reported<br><br>​
Blizzard [7]

Answer:

y = 1

Step-by-step explanation:

Slope is written in the form y=mx+b. Where m is the slope and b is the y-intercept.

When there isn't a slope, as in the line is flat and it isn't moving up or down, you wouldn't write anything for it. You would just write y equals the y-intercept (y = b).

Likewise, if the y-intercept is at (0,0), then you'd only write y equals the slope (y = mx).

Hopefully this makes sense :)

Btw, I also answered in the main comments earlier, so you can check that out as well.

2 Original amount: 30

End amount: 45

<h3>(45 - 30)/30 x 100 = (15/30) x 100 = 50% increase </h3>

3 Original amount: 625

End amount: 550

<h3>550/625 =550 ÷ 625 =0.88</h3><h3>0.88 =0.88 × 100/100 =(0.88 × 100)/100 =88/100 =88% decrease</h3>

4 Original amount: 320

End amount: 112

<h3>(112-320):320x100 =</h3><h3>100 =(112:320-1)x100 =</h3><h3>100 =35-100 = -65% decrease</h3>

5 Original amount: 165

End amount: 222.75

<h3>165/222.75 =165 ÷ 222.75 ≈0.740740740740741</h3><h3>0.740740740740741 =0.740740740740741 × 100/100 =(0.740740740740741 × 100)/100 ≈74.074074074074/100 =74.074074074074% ≈74.07% Increase </h3>
