4. Yes because a function is a expression, rule, or law that defines a relationship between one variable and another variable which is what is happening in this image
5. Yes the slope is shown on the graph because it shows the measure of its steepness which can be determined by simply looking at the image
-12x + 7 just subtract 14 and 2 because they both have x
Answer:
the formula to find slope is m=y1-y2/x1-x2
using this formula 8-6/8-(-4)
=2/8+4
=2/12 simplify
=1/6
