If the equation is 3x + 4y = -1
How would you find two points on that line to graph it?
Hi ZettaDigit,
Assign some arbitrary values for x and solve for y.
Or...find the x and y intercepts.
For instance, let x = 0
Then 3(0) + 4y = -1
0 + 4y = -1
y = -1/4
Point (0, -1/4)
This is actually the y-intercept.
To find the x-intercept, you would set y = 0 and solve for x.
