you can either graph it or solve it algebraically

move the parts of the equation to fit the sctructure of y = mx + b

2x + 4y = 20

4y = -2x + 20

divide by 4 on both sides to get 'y' by itself

y = -2/4x + 20/4

y = -1/2x + 5

this equation tells you the 'y intercept' and the slope

slope; -1/2

y intercept; 5
