£66 because 60/10=6 60+6= £66
To find the slope of a line, we must find the change in y values divided by the change in x values, given by the formula y2-y1/x2-x1 and represented by the variable m. We use our values from the ordered pairs to compute the slope, as follows:
m = (5-1)/(4-2) = 4/2 = 2
Therefore, the slope is 2. Because the slope is positive, this means that the line is rising.
Hope this helps!
Multiply like this. And it gives you your answer.
7.8•7.8•7.8
C (third graph, the parabola); To find if it is a function or not draw a vertical line on the graph. If the vertical line could never intercept the figure more than once anywhere on the graph then it is a function.
