Hi,
2x + 5y = 15
Subtract 2x on both sides.
5y = -2x + 15
Divide every term by 5. Reduce.
y = -2/5x + 3
-2/5 is the slope. 3 is the y intercept.
I hope that helps!! :-)

The equation of a line is almost always shown in the format y = mx + b, where m is the slope and b is the y-intercept. Thus, the equation would be written 5 y = -2x + 15.

Slope intercept form: y=mx+b
5y=-2x+15
y=(-2/5)x+3

Slope intercept form is
y = mx + c
2x + 5y = 15
5y = -2x + 15
y = -0.4x + 3

y=-(2/5)x =3
