Write the point-slope form of the line passing through (3,5) with a slope of -3

The point slope form that passed through (3,5) with a slope of -3 is y=-3x+14

Step-by-step explanation:

y-y=m(x-x¹)

y-5=-3(x-3)

y-5=-3x+9

+5 +5

y=-3x+14

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

just get this app called photo math it should be able to do those
