    what kind of graph? a line or a graph of some equation that curves?

    I assume you are given a picture, or at least two points on the graph?

    I see 5 points on that graph pick any two of those points (it doesn't matter which) and list out the coordinates like so: (x,y) write that out and I will tell you where to go from there

    I will give you one: at x=1, notice that if you follow the blue dot above it to the left you get the y-coordinate which is 10

    so that point on the upper-right corner is (1,10)

    that means that when x=1, y=10 find another point using the same method

    x=-2,y=5 ?

    careful, I think it's x=-2,y=-5 notice we are below the x-axis, and whenever that is the case y is negative

    so now we have two points let's call them (x1,y1) and (x2,y2) it does not matter which is which (-2,-5) and (1,10) are our points

    given two points on a line, (x1,y1) and (x2,y2) the slope is given by\[slope={y_2-y_1\over x_2-x_1}\]so just plug in the numbers into the formula and you get the slope
