the first one is left and the second one is up
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>

Answer: ? = -22.5
Step-by-step explanation:
Using a negative number to replace the ? turns the minus into a plus sign.
-21 - (-22.5) = 1.5 is the same as -21 + 22.5 = 1.5
