Answer:
y=4x+1
Step-by-step explanation:
to find the slope (m) you have to calculate what rise over run is for you table, in this table rise (y values) go up by 4 every time. so thats the numerator for your slope. the run is how much the x value goes up everytime, it goes up by 1 so the denomenator is 1, this simplifies to 4 so m= 4. the y intercept (b) is the y point where x equals zero so it is 1. x and y are simply variables used when graphing so they have no set values.
Answer:
Step-by-step explanation:
Take the 50 and multiply by 1.1 (this is 10% if you dont want to go .1 and add that to 50)
