Answer: y = 3x-10</h3>
==============================================================
Explanation:
Select any two points from the diagonal line. I'll pick (0,-10) and (2,-4).
Use these points in the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-4 - (-10))/(2 - 0)
m = (-4 + 10)/(2 - 0)
m = 6/2
m = 3
The slope is 3.
The y intercept is b = -10 since this is the location where the diagonal line crosses the vertical y axis.
The values m = 3 and b = -10 have us go from y = mx+b to y = 3x-10

Answer: 7 , 13/3
Step-by-step explanation:
300,000 or three hundred- thousand. :)
Y= 3.94x Y is representing the total amount of money owed and x represents how many pounds of blueberries.
Y - 4= 3/4(x + 5)
y - 4= - (3/4)x - 15/4
y - 16/4= -(3/4)x - 15/4
y= - (3/4)x + 1/4
the answer is b
