Question 69294
One simple way is to plot the x-intercept and the y-intercept on your coordinate graph paper (with the x- and y-axes drawn in), then draw a straight line between the two points.
The x-intercept is found by substituting y = 0 and solving for x.
The y-intercept is found by substituting x = 0 and solving for y.
x-intercept:
{{{2x+5y = 10}}} Let y=0
{{{2x = 10}}} Divide both sides by 2.
{{{x = 5}}} The x-intercept is (5, 0)
The y-intercept:
{{{2x+5y = 10}}} Let x = 0
{{{5y = 10}}} Divide both sides by 5.
{{{y = 2}}} The y-intercept is (0, 2)
Now plot these two points on your graph, draw the line and you're done.
