Question

Solve this system of equations by graphing.


y = 7/6x + 2


y = -5

Answer 1

solution: (-6, -5)

given:

`\sf y = (7)/(6) x + 2`

`\sf y = -5`

as both y are equal, solve them simultaneously:

`\sf \sf -5= (7)/(6) x + 2`

`\sf \sf -5-2= (7)/(6) x`

`\sf \sf -7= (7)/(6) x`

`\sf \sf -7(6)= {7}{} x`

`\sf \sf -42= {7}{} x`

`\sf \sf -6= {}{} x`

`\sf given: y = -5`

`\sf so \ solution : (-6,-5)`
