Answer:
Below in bold.
Step-by-step explanation:
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
y - (-1)) = -2/5(x - -10)
y + 1 = -2/5(x + 10)
y + 1 = -2/5x - 4
y = -2/5x - 5.
In standard form this is:
2x + 5y = -25.
Again
1000kg = 1ton
3000kg = 3 tons
Answer: (30-18)=-9 First, I multiply the 3 to the 10. Then I solve what's in the parentheses which was -3 × 2 which got me -6.
