Explanation:
Ok for example with the graph below. You want to find the slope. The slope of this graph is 4/5, because I did the technique rise over run. You want to find a point on the line that is in the middle of a square and then find another point and measure. Go up until it meets the other and then go left or right depending on the direction of the line.
After you find the slope you want to find the y-intercept. To find the y-intercept take any point on the line and plug it into this formula with the slope: y=mx+b
So I took the point (0,3): 3=(4/5)(0)+b
Solve: 3=0+b
3=b
And then wen u have all the right material for your equation, you can plug it all in, which gets me: y=4/5x+3
