IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
$$m=\frac{y_2-y_1}{x_2-x_1}$$

standard formula
$$Ax+By=C$$

point-slope formula
$$y-y_1=m(x-x_1)$$

slope-intercept formula
b= y-intercept -- in the form of (0,y)

$$y=mx+b$$

you're given the slope and y-intercept of the graph, so you can easily find the slope intercept form of the graph.

in order to test, whether (2,2) is on the line, you substitute that point into the slope intercept equation and determine whether or not it makes sense

if it makes sense then 2,2 is on the line, if not, then its not on the line
