Answer 1

first find y-intercept
y-intercept where line touch y-axis
so look at the graph and see where line touch y-axis whts that point ??

Answer 2

okay

Answer 3

so whats that point where line is crossing y-axis ?

Answer 4

Find where the line first intersects with the Y and the X, find those coordinates. So the line passes through Y at (0,-3) and passes through the X at (3,0). Put this in the slope formula. That is the formula. After you get the slope. you take one of the coordinates and then "plug it in" into slope intercept formula which is Y=MX+B
