Step-by-step explanation:
We know that the graph passes through the point 
, since the line crosses the X-axis at 
, so that means our equation has 
in it. The graph also passes through the point 
, so the equation also has 
in it.
This narrows it down to options C and D.
When a graph "bounces" off the X-axis at a point, like it does at 
, this is called a "double zero", meaning two factors of the equation equal zero. This means that the graph has 
, leaving us with option D.
6a - 2a = 4a
2b + 3b = 5b
Therefore 4a + 5b is the answer.
The correct answer is y = -2x + 16. In slope-intercept form, the formula is y = mx + b, where m is the slope and b is the y-intercept, or the place where the line crosses the y-axis. For this line, the y-intercept is positive 16, because the line crosses the y-axis at 16. Therefore, we know that the equation is y = mx + 16. Now, we just need to find the slope. By counting squares, we can see that the line goes down 4 and right 2. You can check this by taking two points on the line and subtracting them. For instance, the line goes from y 16 to y 12, which has a 4 unit difference. Therefore, the line goes down 4. It goes from x 0 to x 2, meaning that there is a difference of 2 between them, and, since the line is going right, the 2 is positive. Since slope = y/x, the slope is -4/2, or -2. Therefore, the slope is -2.
Adding all this together, the slope in slope-intercept form is y = -2x + 16.
Hope this helps!
