I took the slope intercept form equation: y = 1/2x + 7, and transformed it into general form. This what I ended up with: -1/2x + y - 7 = 0. Because I am new to this type of math, I checked my work in the back of my math book. It turns out that the real answer is supposed to be: x - 2y + 14 = 0. I can not figure out how to get that answer. Can I get a step by step explanation on this?

It is x-2y+14=0, because from y=1/2x + 7. You subtract y on both sides of the equation, so there for you would have 1/2x - y + 7 = 0. And from there you would have to get rid of the fraction, so you would multiply by its reciprocal 2/1. Which is how you get x - 2y + 14 = 0.

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

answer: ok
