Question

Find the slope and​ y-intercept of the line whose equation is 2 x plus y equals 3 (2x+y=3).

Answer 1

You can solve this equation by rearranging the 2x to the opposite side, but since it's a positive, you must change it to a negative. If the number was negative, it would've been a positive.
y=-2x+3
-2x is the slope and 3 is the y-intercept.
