# 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... ## Best Answers: How do I find the slope of a line? Addy | 5 days ago
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 Originally Answered: Find the generalform of the equation of the line that pass through the given point and has the indicated slope?
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. Tanner
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 Originally Answered: Write the equation of a line in slope-intercept form that is parallel to the line y=1/2x+7 and containing po?
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
