Using the slope intercept form of a line find the equation of a line with a slope of 4/3 in a y intercept of negative one. then graph the line on the grid provided in explain how you determine your graph

Hello:

equation is the line is : y = ax+b        a is a slope

y = (4/3)x+b

passing through the point (0;−1) :   -1 =(4/3)(0)+b   so : b = -1

y = (4/3)x-1

you can determine your graph by the point (0 ; -1) and another point ( 3/4 ; 0)

for exempl  when y = 0    you have :  (4/3)x-1 = 0  so :  x = 3/4

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
