We have to find the value of the expression
We know that the below values.
Hence, in order to find the value of the given expression, we can first rewrite it in terms of
Now, we know that
Hence, we have
C is the correct option.
The equation to find the slope is the y coordinate for the first point minus the y coordinate for the second point over the x coordinate for the first point minus the x coordinate for the second point.
(Note: the image is the equation for the slope. it doesn't always have to be
y1-y2 over x1-x2, it can also be y2-y1 over x2-x1 but those are the only 2 equations.
So, the equation is (4-3)/(1-0) because the y coordinates are 4 and 3, the x coordinates are 1 and 0.
(4-3)/(1-0)=1/1=1 so the slope is m=1
Now you do the same thing for the next problem:
(-1-0)/(-2-0)=1/2 so the slope is m=1/2
