Sustitute x = 0 in to the equation to fin y axis intercept
4(0) + 5y = 20
y = 4 = y axis intercept
Sub y=0 for x axis intercept
4x +5(0) = 20
x =5 = x axis intercept
4x+5y =20 subtract 4x from both sides
5y = -4x + 20 Divide both side by 5
y = -4/5 x + 4 = y=mx+b slope intercept form
Substitute x = 0 in to the equation for the y axis intercept
Sub y=0 x axis intercept
re-arrange the equation into y = mx+b form for slope intercept form.....
OK? Need more hints?
