so... for the beginning m = 1 cause your slope is just rising and running one everyone time. This makes the equation
[tex]y = x + 2[/tex]
Then for the next question your y value is determined to when x equals 0. This means that y equals -3. To find the m (slope) divide
[tex] \frac{y}{x} [/tex]
for example
[tex] \frac{5}{2} = 2.5[/tex]
That would be your slope line.
The two points can be any (x,y) points from the table.
Have fun.
