How do you find x intercept?
to find the y-intercept you plug in your x and y values in to the equation of y=mx+b. b is the y intercept and m is the slope. To find the x-intercept, set y = 0, and find value of x that satisfies the equation. If it is a line in the form y=mx+b, then the x-intercept will be at x= -b/m
How do you find the straight line equation passing through the points -7 -3 and -1 -4?
First find the slope and then use the fact that y = mx+c where m is the slope and c is the intercept on the y axis to find the equation. Slope: -4 - -3 over -1 - -7 = -1/6 Equation: y = -1/6x -25/6 or 6y = -x -25
What is the equation that show the relationship between coordinates of points on a line called?
It is a straight line equation in the form of y = mx+c whereas m is the slope and c is the y intercept
How do you find the scale factor of the exponential equation?
m=24*(1.135)*1
When given an equation of a line an a point not on that line what are the steps to writing an equation that's through that point and parallel to that line?
If you represent the original straight line on a graph using Cartesian co-ordinates, it's equation will be y=mx+c where y and x are the variables and m and c are constants. (m will equal the gradient of the line. c will be the point where the line cuts through the y axis). Your new line, parallel to the original will be y=mx +c +d where d is the vertical distance between the point and the original line.
How to find the equation of a line?
Equation of a line may be written as y = mx + c. m is called the slope of the line. c is the point where the line crosses the y axis. If two points are given: (x1, y1) and (x2, y2), m is calculated as the y difference divided by the x difference: m = (y2 - y1) / (x2 - x1) Once you find m, you can find c by putting in the values into the equation y=mx+c. For example, if you use (x1, y1), you can do this: y1 = m*x1 + c take m*x1 to the other side: y1 - m*x1 = c Then you get the value of c. Now you have both m and c, so you can write the equation of the line: y = mx + c Put the values of m and c in. Leave y and x as it is. a.net/math_problems/equations-of-lines-problems-with-solutions.html
What letter represents slope on slope-intercept equation?
The equation of line in terms of y , x coordinates and intercept can be written as : y= m x+ c where m is the slope of the equation and the c is value of intercept.
How can you find slope of a line from an equation?
y=mx+c c is the y axis intercept. M is the gradient. The slope of the line is equivalent to m
Find m when y equals 3x plus 3?
For the equation y = 3x + 3, the value of m (the slope) is 3.
What does 48,000 = m?
The expression "48,000 = m" is a mathematical equation that uses the variable "m". This equation states that "m" is equal to 48,000. In other words, the value of "m" is 48,000. It's important to note that in mathematics, equations use the equals sign (=) to indicate that the value on the left side of the equation is equal to the value on the right side of the equation. In this case, the value of "m" is equal to 48,000.
What does e equals m c square mean?
e = energy m = mass c = the speed of light The equation is e=mc2 (where 2 means the value of c is squared) This means that if a value, or amount of mass, is multiplied by the square of the speed of light, the resultant value equals an equivalent amount of energy.
Is y equals 5x² a linear equation?
A linear equation is of the form y=mx+c, where m and c are constants. Therefore, y=5x is a linear equation. Here m=5 and c=0.
-m-5n what is the value?
The value of M in the equation -M take away 5N would be 15. This is math.
How do you find the gradient of a Linear Equation?
If necessary, rearrange the linear equation so that it is in the slope-intercept form: y = mx + c Then the gradient of the line is m.
How do you find the x and y intercepts of a linear equation in standard form?
The y-intercept is c in the standard form. The x-intercept is -c/m.
How can you find equation of the line passing thruogh two points?
. the equation of a straight line can be found by using two points on a line . First find the gradient of the line using the gradient formula . now substitute the gradient into general form replacing "m" . use one of the points and substitute into equation to solve "c" example 1: find the equation of the line which passes through the points (1,3) and (2,5). step 1: find the gradient M=5-3/2-1=2 (/=divide) step 2: place m into the equation Y=2x+c step 3: substitute point into equation 3=2(1)+c step 4: solve C=1 equation is Y=2x+1 hope that helps :)
