You are very close but you need to put the slope and y-intercept together to create the Slope Intercept Form.
Remember it’s y=mx+b (which is already on your notes). First, but on the m= the slope you figured out, next put the x beside the slope, last, put in the b= the y-intercept you figured out.
In conclusion, your answer should be
y=-2x+10
Hope this helps! :)
