I'll do the first two to show you how to do these

#42
If we have the statement f(2)=-3, this means we have the point (2,-3). Also if we have the statement f(-2) = 5, this means we have the point (-2,5)

Now let's find the slope through (2,-3) and (-2,5)


Solved by pluggable solver: Finding the slope


Slope of the line through the points (2, -3) and (-2, 5)



m+=+%28y%5B2%5D+-+%28y%5B1%5D%29%29%2F%28x%5B2%5D+-+x%5B1%5D%29


m+=+%285+-+%28-3%29%29%2F%28-2+-+2%29


m+=+%285+%2B+3%29%2F%28-2+-+2%29


m+=+%288%29%2F%28-4%29


m+=+-2



Answer: Slope is m+=+-2








#44:
If we have the statement f(-3) = -9, this means we have the point (-3,-9). Also if we have the statement f(-1) = 2, this means we have the point (-1,2)

Now let's find the slope through (-3,-9) and (-1,2)


Solved by pluggable solver: Finding the slope


Slope of the line through the points (-3, -9) and (-1, 2)



m+=+%28y%5B2%5D+-+%28y%5B1%5D%29%29%2F%28x%5B2%5D+-+%28x%5B1%5D%29%29


m+=+%282+-+%28-9%29%29%2F%28-1+-+%28-3%29%29


m+=+%282+%2B+9%29%2F%28-1+%2B+3%29


m+=+%2811%29%2F%282%29


Answer: Slope is m+=+11%2F2
