here's the solution,
- n = 11
- a = 5 ( a = first term )
- d = 6 ( d = common difference )
we know,
=》
=》
=》
=》
=》
nth term ( 11th term ) = 65
So first, you need to identify the parts of this equation.
3x is the slope of the line, which is .
-5 is the y-intercept. or the part of the line that touches the y-axis.
The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.
Now, use the slope to find your next plot. Since slope is
, you go up three, and over to the right one.
Now, draw a line connecting the dots. Your slope should be positive and look like > /
