First we find the slope between the two given points.
m = (y2 - y1)/(x2 - x1) = (-5 - 2)/(7 - 6) = -7/1 = -7
Now we use the slope-intercept equation of a line.
y = mx + b
We use one point as x and y, and we solve for b.
2 = -7(6) + b
2 = -42 + b
b = 44
The equation is
y = -7x + 44
Answer: f(x) = -7x + 44
Hey there! I'm happy to help!
This is a solution because x has the same value as y. They are both 6.
I hope that this helps! Have a wonderful day! :D
So he is paid 46.5 flat every day
he earns 5% of each smart phone he sells
at the time of the problem, smart phones sell for 70 so he earns 5% or 70 or 5/100 of 70 or 1/20 of 70 or 70/20 or 7/2 or 3 and 1/2 or $3.50 per phone he sells
so pay must be at lease 150 so
pay=46.5+ (# of phones times 3.50)
150<u><</u>46.50+(number of pones times 3.50)
solve for number of phones
subtract 46.5 from both sides
103.5<u><</u>(number of phonest imes 3.5)
divdie both sides by 3.5
29.57<u><</u>number of phones
round up since can't sell a fraction of a phone
30
he has to sell at leas 30 phones
