The required equation of a line is y = 9/5 (4x - 12)
Given-
The point from which the line passes through is (3,2)
The slope of the given line m is -4/5.
Equation of the line
The linear equation of a line can be represented by a set of points on a graph using the equation of the line.
The standard form of the line passing through the point x₁, y₁
The slope m is given by,
m = (y - y₁) / (x - x₁)
Put the values of points and slope in the above equation, we get,
-4/5 = (y - 2) / (x - 3)
-4/5(x - 3) = y -2
-4x/5 + 12/5 = y - 2
-1/5 (4x - 12) + 2 = y
y = 9/5 (4x - 12)
The linear equation of a line can be represented by a set of points on a graph using the equation of the line. The following equation depicts a line that crosses (3, 2) and has a slope of -4/5: y = 9/5 (4x - 12)

Answer:
- 14 coins of 5p
- 11 coins of 20p
Step-by-step explanation:
<u>Given</u>
- 5p coins = x
- 20p coins = y
- Total = 2.90 = 290 p
- Number of coins = 25
<u>Equations</u>
- x + y = 25
- 5x + 20y = 290 ⇒ x + 4y = 58
<u>Consider the first equation in the second one</u>
- x + y + 3y = 58
- 25 + 3y = 58
- 3y = 33
- y = 11
<u>Then x is</u>
<u>Answer</u>
- 14 off 5p coins and 11 off 20p coins
