Answer 1

Slope-Intercept: y = mx + b  ; where "m" is the slope and "b" is the y-intercept

Start with "b".  Where does the line cross the y-axis?  at 0

Next, look at the slope.  Pick two point and count the rise over run. Let's use the points (2, 5) and (4, 10).  The rise = +5 (up 5 ) and the run = +2 (right 2)

$\frac{rise}{run} = \frac{5}{2}$ = 2.5

Now, plug in the "m" and "b" into the Slope-Intercept formula:

y = 2.5x + 0  ⇒  y = 2.5x

Answer: C

Note: you can also use the slope formula to find "m": m = (y₂ - y₁)/(x₂ - x₁)
