It is the equation of a line....when x= 0 you will find the y-axis intercept when in y=mx+b form
x + 5y = 10
5y= -x +10
y = - 1/5 x + 2
y= -1/5 (0) + 2 y intercept = 2
when y = 0 you will get the x-axis intercept
0 = -1/5 x + 2 x intercept = 10
Plot those points and draw a lint through them.... ta da! done! I will get a picture in just a sec...
As an afterthought, you do o not have to change it to y = mx+b form
x = o gets y axis intercept 0 +5y = 10 y = 2 = intercept
y=o gets x axis intercept x + 5(0) = 10 x = 10 = x axis intercept....
Either way works ! D'Oh !
