HELP ME Which properties can be used to solve 7y − 15 = −29? Select all that apply.

Step-by-step explanation:

Using the additive property of equality, we add 15 to both sides of the equation.

Using the inverse property of multiplication, we divide both sides of the equation by 7.

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

i need on these three questions. find standard form equation of line perpendicular to y = (2/3)x - 8 that goes through the point
