Where m is the slope and b is the y-intercept. So the equation is
Here's the graph of and
Write the equation of the line L satisfying the given geometric conditions.
L has y-intercept (0, -3) and is parallel to the line with equation y=2/3x+1.
Slope - Intercept formula
y = mx + b, where m = slope and b = y-intercept
Remember that if the lines are parallel to each other,
The slope are equal.
Since a line y = (2/3)x + 1 is parallel to the line we are looking for,
m = 2/3 and according to the given y-intercept = -3
so the equation of the line we are looking for is
y = (2/3)x - 3
If you want to see the graph, here it is
The red line is the graph of y = (2/3)x + 1
The green line is the graph of y = (2/3)x - 3
Notice that the line are parallel to each other.
