4-74.

Write an equation (rule) for each of the $x → y$ tables below. Then, on one set of axes, use each rule to graph. 4-74 HW eTool (Desmos).

1.  $x$ $y$ $8$ $23$ $2$ $5$ $−3$ $−10$ $9$ $26$ $x$
1.  $x$ $y$ $6$ $32$ $−2$ −8 $0$ $2$ $10$ $52$ $x$

Graph the given points.

Draw a line through the points.
If the line represented a tile pattern, how many tiles would be in figure 0?
How would the pattern be growing?

In part (b), figure 0 has $2$ tiles.The pattern grows by $50$ tiles every $10$ figures.

$y = 5x + 2$
