What is the slope (gradient) of
8x-4y=12
Get Eq. 1 into y = mx + b format:
8x - 4y = 12
-4y = -8x + 12
Divide each side by -4
| -4y |
| -4 |
| = |
| -8x + 12 |
| -4 |
Simplifying, we have:
y = 2x - 3
Final Answer
Slope = 2
Calculate the y intercept of our line
The y intercept is found by
Setting x = 0 in
y=2(0)-3
y-intercept = 0-3
y-intercept = -3

How does the 2 Lines Intersection Calculator work?
Free 2 Lines Intersection Calculator - Enter any 2 line equations, and the calculator will determine the following:
* Are the lines parallel?
* Are the lines perpendicular
* Do the lines intersect at some point, and if so, which point?
* Is the system of equations dependent, independent, or inconsistent
This calculator has 2 inputs.

What 3 formulas are used for the 2 Lines Intersection Calculator?
Lines are parallel when they have the same slope.
Lines are perpendicular when they have slopes which are negative reciprocals.
For a line y = mx + b, m is the slope
Lines are perpendicular when they have slopes which are negative reciprocals.
For a line y = mx + b, m is the slope
