This is asking for slope intercept form. See attached
[Slope]
The slope is -
.
-> Start at (0, 0)
-> Count four units down and three units right to the next point
-> Since this line is going from top left to bottom right, the slope is negative
[Y-intercept]
Since this line goes through the orgin, (0, 0), there is no y-intercept. Hence why this value is nonexistent in the equation they give to fill out.
Answer:
To fill it in for your assignment, see attached or read below;
The slope itself should be negative, so enter a "-" (or however you do it)
The question mark, outlined in green, should be 1
The top of the fraction, the numerator, should be 1
The bottom of the fraction, the denominator, should be 3
