Find the equation of the line
passing through the points. (5, 2) and (10, 6).??

y=(4/5)x-2

Assuming this is a liner function, you must first find the slope through the point slope formula [(y2-y1)/(x2-x1)]. When you plug in the corresponding values [(6-2)/(10-5)], your slope value should be 4/5.

After this, apply the slope to the x-values to find the intercept. For example, 10 x 4/5 is 8. To get to 6, you must subtract 2. This means your intercept value is -2

Therefore, your equation is y=(4/5)x-2

Step 1: Find out how many kilograms of onions Hiro will use. 
(1 gram= 0.001 kilogram)
550 grams= 0.55 kilograms

Step 2: Find out how much produce was not used for potatoes and onions
5 kg- 3.25 kg = 1.75 kg
2 kg-0.55 kg= 1.45 kg

Step 3: Add together the unused produce.

1.75 + 1.45= 3.2 kg were not used.
