How do I find the slope of a line?

How do I find the slope of a line? Topic: How to write an equation parallel through a point
July 17, 2019 / By Barb
Question: I'm really stuck with some Algebra problems dealing with slope... I have no clue how to do any of this. I need a walkthrough of how to solve these prolems: 1. What is the slope of a line parallel to to the line 2x + 3y = 7 2. Write an equation for the line passing through the point (-5,-2) and has a slope of -3. 3. State the relationship between the lines y = -1/3 x + 2 and y =1/3 x -2 I'm not looking for answers as much as I am looking for ways of how to actually do these problems. Any help would be great. Thanks for the answers... but I need to know how to actually do the problems...

2x+3y=7 -2x -2x 3y=-2x+7 y=-2/3x+7/3 2) y+2=-3(x+5) y+2=-3x-15 -2 -2 y=-3x-17 3)it's perpendiculars problem because their the opposite

Memorize this equation: y = mx + b where: y = dependent variable x = independent variable m = slope of the line b = y-intercept. The numbers inside the parenthesis are the coordinates of a given point. The first number is the x variable, the second number (-2) is the y variable (x,y). Since the x variable is 0, this point is the y - intercept. (If a given point has a 0 x variable, the point is the y-intercept) Then substitute the m (slope) and the y-intercept to the equation. What is the y-intercept? It is the point that passed through the x-axis. y = mx + b y = 3x + -2 Derive your equation to the general form where the whole equation is equated to 0: 3x - y - 2 = 0 This site will help you with your assignment. Actually it might answer the problems in your homework. But I advise that you master how to solve these problems. http://www.webmath.com/equline3.html

y=mx+b -2=3(0) + b b = -2 y = 3x - 2 You substitute the x and y values and the slope and then you put the equation into y=mx+b form to solve for b. From there you rewrite the equation so you only have b and m as numbers and the rest is x and y.

since you are dealing with some simple numbers (no fractions or decimals) you could just graph it on some graph paper and just do it all physically with a ruler,,, that works for me cause i suck at stuff like this =(

We are looking for a line of the form y = mx + b If your line is parallel to y = (1/2)x + 7, then your line will have the same slope. So our new line will have the slope (m) of 1/2. Using the point they gave us, we now have plenty of information. m = 1/2 x = -4 y = 7 y = mx + b 7 = (1/2)(-4) + b 7 = -2 + b Add 2 to each side 9 = b So m = 1/2 and b = 9 y = 1/2x + 9

the line parallel to y = (7/8)x - 7 also has the slope 7/8 and so will be of the type ... y = (7/8)x + c to discover the price c we plug contained in the provided values for x and y from the point (8,0) ... 0 = (7/8)8 + c hence c = -7 so the equation is y = (7/8)x - 7 i.e. a similar line
