How do you graph the equation by plotting points #3x + 5y = 12#?
2 Answers
First get the equation into standard form:
Then, start plugging in values for
Explanation:
Getting the equation to standard form
It will be much easier to plug in values if the equation is in standard form (so that
Next, divide each side by 5 to isolate
You can do the distributive property to get it to truly standard form, but it'll be pretty easier from here.
Pluggin' in values
I always find it helps to make a table, but however you want, find a way to record. Pick a simple value for
Work that out...
Try another! Let's have
Well,
graph{y = (-3x +12)/5 [-8.89, 8.89, -4.444, 4.445]}
Express the equation in the point-slope form, i.e, y = mx + c.
Explanation:
Now put values of x in the equation and get corresponding values of y. Plot the graph according to the values you get.
For example :
when
when
when
graph{(-3/5)*x+12/5 [-7.174, 6.87, -1.386, 5.644]}
