Step-by-step explanation:
how the elevation of city can be seen below the sea level
Answer:
The answer is y=-x+9.
The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9
First, we obtain the gradient (slope) of the first parallel line
Recall that since both lines are parallel, we have that,
Thus
Hence, we can find the equation of the parallel line given that it passes through the points (-4, -3)
Using
