Slope of a graph where the y intercept is 0,5 and another point is 1, 27?

To find the slope, you need to points of a line. These points (in this case) are (0,5) and (1,27)
There is a formula to figure out slope.
That is-

Slope= y1-y2

x1-x2

What the equation is saying is that you subtract both the y coordinates and then subtract both the x coordinates. Finally, you divide the y coordinates by the x coordinates.

5-27=-22
0-1=-1

-22/-1=22

The slope is 22
