How do I solve this graph 10x-20y+16=0

10x - 20y + 16 = 0

- 16 - 16

10x - 20y = - 16

10x - 10x - 20y = - 16 - 10x

-20y = - 16 - 10x

-20 - 20

y = 0.8 + 0.5x

Forst you want to get y by itself on one side of the equation

20y=10x+16

then you want to isolate y so its coefficient is 1

y = (1/2) x + (4/5)

then you graph. if youre looking for where it crosses the x and y axis you make y 0 and solve for x to find where it crosses the x axis and make x zero and solve for y to find out where it crosses the y axis
