What does the phrase rise over run refer when defining slope?
This is the fraction or number representing how many units up a line goes for ever unit it goes laterally. For example, a slope of 2/3. This line goes up two units for every three it goes sideways.
How do you solve slope and equations?
The slope is the rise/over run of a line. The equation of a line is usually written in the form y=mx+b where m is the slope and b is the y-intercept. To find the slope, you can take two points on a line, find how much the line goes up (or down) between the two, and divide it by how much the lines moves to the right. Usually the slope is left in the simplest fraction form.
Slope intercept form of (-23) (1-1)?
HOW TO FIND THE SLOPE AND Y-INTERCEPT OF A LINEto find the slope, you need 2 coordinates on the line. So, 2 sets of (x, y) which will be:(x1,y1) and (x2,y2) you will then perform the following to find the slope of the line(y2-y1)/ (x2-x1). (so you do y2-yi divided by x2-x1) This is how you find the slope.If you want to find the y-intercept (represented by the variable b), substitute one of your given points (from question 1) and your slope (which is represented by the variable m) into this equation:y= mx + bSo, you know the values of x, y (your coordinates) and m (your slope). Substitute the values to solve for b. Then, this will be your final equation of the line.Remember that if the lie goes down from left to right, the slope is negative. If the line goes up from left to right, the slope is positive.* Important To Remember*-If the line is horizontal, the slope is zero-If the line is vertical, the slope is UNDEFINED-If a line goes vertically on the x- axis the equation will be "x = that number that crosses the x- axis" since the line will not have a y-intercept since it doesn't cross the y- axis.*TIPS*When doing questions with slopes and y-intercepts, graph the line first!
What is the slope of a line?
The slope of a line refers to how steep the line is. Given two points, (x1,y1) and (x2,y2), the slope can be found by this formula: (y2-y1) / (x2-x1). If the number is positive, the line goes up. If the slope is negative, the line goes down. If the slope is zero, the line is horizontal and if the slope is undefined because the denominator is 0, the line is vertical.
What is the point-slope equation of the line with slope -10 that goes through the point 14?
It is: y = -10x+14
What is the slope of y equals 5x plus 8?
5/1 Because: y=mx+b is your basic formula. Variable m being the slope, which is mostly a fraction. 5 being in fraction form is 5/1 because 1 goes into 5 5 times. Variable b is the y intercept, the y axis in which the slope goes through on the y origin.
What does the phrase rise over run refer when defining slope?
This is the fraction or number representing how many units up a line goes for ever unit it goes laterally. For example, a slope of 2/3. This line goes up two units for every three it goes sideways.
What does slope describe?
the change of rise over run. a positive slope goes up and a negative slope goes down
When constructing a graph which variable goes on which axis?
The independent variable goes on the x-axis and the dependent variable goes on the y-axis.
What is the positive slop?
A positive slope goes upwards whereas a negative slope goes down wards
Which variable goes on the x axis?
The independent variable goes on the x axis.
What variable goes first in the title of a line graph for science?
The independent variable typically goes on the x-axis and the dependent variable goes on the y-axis in a line graph for science.
What is the equation of a line in general form with a point -3 0 and an undefined slope?
You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.
On which axis of a graph should the independent variable be graphed?
the independent variable goes on the x-axis the dependent goes on the y-axis
How do you determine which variable goes on the y-axis?
the dependent variable goes on the y- axis
What variable goes on the y-axis?
dependent variable
What variable goes on the y axis?
dependent variable
