WebBy setting them equal to each other, you can find the value of x. To set them equal, what you need to do is place the equations on either side of an equal sign. (8x-184=4x-148) By doing this, you indicate that the sides are equivalent. Then, you solve for x by, in this example, adding 184 to negative 148.

Weby = m1x + b1. y = m2x + b2. then the slopes are m 1, m 2 and the y-intercepts are b 1, b 2. To show that two lines are parallel, we need: m1 = m2 ( the two lines have the same slope) b1 != b2 (the two lines have different y-intercepts) Let’s look at some examples. WebJan 18, 2024 · The two lines are determined to be parallel when the slopes of each line are equal to the others. If the comparison of slopes of two lines is found to be equal the lines are considered to be parallel.
