You can put this solution on YOUR website! find the equation of the line which passes through the point ( -2, 1 ) and is parallel to the straight line with the equation 2x - y - 3 = 0?
============
2x - y - 3 = 0
To find the slope, convert to slope-intercept form.
That means solve for y.
---
2x - y - 3 = 0
y = 2x - 3
The slope, m, is the coefficient of x.
m = 2
-----
Parallel lines have the same slope. 2, in this case.
---
An equation, not "the equation," is y - y1 = m*(x - x1)
(x1,y1) is (-2,1) PS don't put spaces in the points.
----
y - 1 = 2*(x + 2)
You can change the format.
y = 2x + 5
Same thing.
