So you basically plot a point of the y axis on 7 then since the slope is -3x you have to go down 3 and to the right 1 and keep going then you have to do the same but opposite, go up 3 times and to the left 1 unit.
Answer:
slope: 3 y-intercept: 9
Step-by-step explanation: 19-10 is 9, and 6-3 is 3 9/3 is 3.
28-19 equals 9. 19-10 is 9, so 9 fills out that blank beside 10.
It's 1.5
