    Is the slope 1 since -1+2 is 1?

    Sorry, i was off in neverland there to a minute. Yes, rate of change is the slope, and yes, i believe so

    that's the difference of x's look at the graph find y value when x=-1 and when x=2 y=? then use the formula to find slope \[\huge\rm \frac{ y_2-y_1}{ x_2-x_1 }\]

    For the graph you go up 4 and over 2. Which is also 1/2. So the answer is B?

    i can't say yes by just looking at that graph but line is increasing so slope would be positive if line decrease= negative slope line increase =positive slope

    remember slope =rise over run so that's how 4 over 2 and 4/2 = what ? :D
