A) y = 2x + 4
Step-by-step explanation:
The slope is 2, as we can see by examining two points, (0,4) and (1,6). The y-intercept is 4. Plug all this in to get A.
Why not B and C: The y-int of the graph is 4, so there must be a +4 in the equation.
Why not D: We know the slope is positive, so this isn't right.
