How do I Graph y= –73x+2 .

Romashka-Z-Leto [24]

Answer:

See attachment

Step-by-step explanation:

You can obtain any two points on the graph of $y=-73x+2$ and use it to draw its graph.

When x=0, $y=-73*0+2=2$

So you plot (0,2)

When x=1, $y=-73*1+2=-71$

You again plot (1,-71).

With a straight edge you can now draw a straight line through the two points.

2. 1000cm

3. 0.0453m

4. 37.5 kg/L

Step-by-step explanation:

1. 1gram (g) =1000milligrams(mg)

5.70×1000=5700mg

2. 1 m= 100cm

10×100=1000cm

3. 1000mm=1m

45.3/1000=0.0453m

4. 1000g=1kg

37.5/1000=0.0375

1000ml=1L

1ml= 1/1000= 0.001L

0.0375/0.001= 37.5 kg/L
