Question 1 Report

ind then equation line through (5, 7) parallel to the line 7x + 5y = 12

5x + 7y = 120

7x + 5y = 70

x + y = 7

15x + 17y = 90

Answer Details

Equation (5, 7) parallel to the line 7x + 5y = 12
5Y = -7x + 12
y = $\frac{- 7 x}{5}$ + $\frac{12}{5}$
Gradient = $\frac{- 7}{5}$
∴ Required equation = $\frac{y - 7}{x - 5}$ = $\frac{- 7}{5}$ i.e. 5y - 35 = -7x + 35
5y + 7x = 70
