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:
infinite points along the line
Step-by-step explanation:
This is the equation for a line. A line has infinite points. So there are infinite solutions along the line
Answer:
Step-by-step explanation:
x = domain, f(x) = range
<u>Look for matching numbers:</u>
- f(4) = 1/2
- f(x) = 4 when x = 8
