Answer:

y = 2x - 1

n = 6

Explanation:

Slope: (7 - 5)/(4 - 3)

= 2/1 = 2

y = 2x + c

5 = 2(3) + c

c = -1

y = 2x - 1

11 = 2n - 1

2n = 12

n = 6

Answer:

Rule: y = 2x - 1

n = 6

Explanation:

Note that for every one of the x values, if we multiply them by 2 and subtract 1, we get the y values.

For example, for (3, 5):

x = 3 and y = 5.

3 * 2 = 6

6 - 1 = 5

So, the rule is that whatever x we have, if we multiply by 2 and subtract 1, we get y: y = 2x - 1

Then, substitute n for x and 11 for y to solve for n:

11 = 2n - 1

12 = 2n

n = 6

Thus, n = 6.

Hope this helps!
