4y+8x=20 passes through (4,6)

Question

Y=mx+b 

Answer 1

Hi Abs,

A bit of confusion here because there seems to be some missing information in the question.

 

If you just need a y=mx+b form of the original equation then you would Subtract 8x from both sides of the equation to get 4y = 20-8x. Then Divide both sides by 4 to isolate y and you get y=-2x+5. The slope and the y intercept are found by rearranging the equation to solve for y.

 

If you need a line parallel to 4y + 8x = 20 that passes through (4,6) then you would set the slope = -2 (parallel lines have the same slope) and then solve for b. As in y=-2x + b, substitute in (4,6) and solve for b.  6 = -2(4) + b and therefore b = 14. The final parallel equation would be y = -2x + 14.

 

Hopefully, one of these answers is what you are looking for.
