Answer:
the answer is C
Step-by-step explanation:
First, let's find the slope of the line using the slope formula, which is:
((, ) and (, ) are points on the line)
In context of this problem, we can use the formula to find the slope of the line between the two points:
Now, we can use the slope in the point-slope formula, which will help us find the final equation of the line. (For reference, the point-slope formula is where (, ) is a point on the line)
In the context of the problem, we could use the formula to find the equation of the line:
The equation of the line is y = -x + 5.
