Slope: 9
Y-intercept: (0,0)
equation: y= 9x
Solving for slope: I used the point (9,1) and I divided 9 by 1 to get the slope (9). this only works when the y-intercept (the point where the line crosses y axis) is (0,0).
Solving for y-intercept: I saw where the line is crosses the y axis, this is always where x is 0
Solving for equation: I wrote the equation is y=mx+b format. m is the slope and b is the y-intercept. Since the y-intercept is 0, I didn't have to add/subtract anything.
