The coordinates of the points A and B are (0,-2) and (3,0), what is the y intercept of the line AB

-2

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form: where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis). To solve this question, first, find the slope, then, plug one of the given points into the equation to isolate b.

1) Find the slope (m)

where the given points are and

Plug in the given points (0,-2) and (3,0)

Therefore, the slope of of the line is . Plug this into   as m:

2) Find the y-intercept (b)

Plug in one of the given points: (0,-2) or (3,0)

Therefore, the y-intercept of the line AB is -2.

I hope this helps!

20% of 120 is 24. if you subtract 24 from 120 you get 96

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
