Shaun collected data comparing the color of his friends' shirts. After plotting the data, he found the line of best fit with the equation y=−7.5x+4.2, where x represents the number of people wearing red shirts and y represents the number of people wearing blue shirts. What does the y-intercept mean in this situation?

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

y=mx+b

step-by-step explanation:

m slope

b y-intercept

answer: .75 km

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !
