The standard form:
The slope-intercept form:
m - slope
b - y-intercept (0, b).
We have the point (0, 43) → b= 43.
Next point (2, 55). Substitute to the slope formula:
Therefore we have:
<em>subtract 6x from both sides</em>
Volume- LxWxH
30x10x50= 15000
9 dived by 3 = 3
so he surfed for 3 hours = 1/3 of 9
and there are 6 hours left
so he spent 6 hours building a sandcastle

Step-by-step explanation:
-5/8 + 3/4
= -5/8 + 6/8
=1/8
