Since y = x+5, we can substitute y for x+5, making the new equation
3x + x+5 =25. Now, you can solve traditionally. 4x = 20, x = 5, y = 10

2x+3y=6 fins the slope of the line
klasskru [66]
2x + 3y = 6

Put this into y=mx+b form (which is also called slope-intercept form)

Where m=slope and b=y-intercept

In order to put this into slope-intercept form, we simply need to subtract 2x from both side.s

3y = 6 - 2x

Then, divide both sides by 3 so that we fully isolate y.

3y ÷ 3 = (6 - 2x) ÷ 3

Simplify.

y = 2 - 2/3x

Put this into order by moving "x" onto the correct place.

y = -2/3x + 2

Therefore -2/3 is the slope, as it is in the "m" spot.

Hope I helped! :)
