How do you find an equation of the line having an x-intercept of 4 and parallel to 2x+Y=2?
This question is asking us about slopes and intercepts. The x-intercept is given and the slope is hinted at by saying that the line we are looking for is parallel to another line. Parallel lines have the same slope.
We can start by finding the slope of the parallel line. Let's use the slope intercept form of the equation of a line to solve this, which is
from which we see that the slope,
Therefore the equation of the line we are looking for is
