I’ll do it, math or reading?
So the rise/run is -4/1 (since the line goes down 4 units when it hits a line directly, and wherever the line hits (in this case unit 1 on the x-axis)). This will be your m. Slope intercept form is y=mx+b, therefore your equation will be y==4/1x+b. to find b, you need to look at where the line hits the y-axis. It hits it at point 4. therefore your final answer will be y=-4/1x+4

Step-by-step explanation:
Answer:
8x + 3(20 - x) = 5(20)
Step-by-step explanation:
If x represents the number of pounds of $8 chocolates, then (20-x) is the number of pounds of $3 chocolates. The cost of the mix attributable to the $8 chocolates will be 8x, and the cost associated with the $3 chocolates will be 3(20-x). The sum of these costs is the cost of the 20 pounds of mix: $5×20.
In equation form, this is ...
8x + 3(20-x) = 5(20)
_____
The solution is x=8, so 8 lb of $8 chocolates should be mixed with 12 lb of $3 chocolates to make a mix worth $5 per pound.
