What is the slope-intercept form of 2x − y 10? Change the equation to slope-intercept form, y=mx+b , where m is the slope and b is the y-intercept. 2x+y=10 Subtract 2x from both sides. y=−2x+10 The slope is −2 .
Secondly How do you know if a slope is positive negative zero or undefined?
Is the equation y 3x in slope-intercept form explain?
This equation is in slope intercept form, and can be rewritten as: y=3x+0 , where 3 is the slope and “0” is the y-intercept.
then What is the slope of 3x y =- 1? Using the slope-intercept form, the slope is 3 .
Is Y 3x slope-intercept form? The slope is 3, the y-intercept is 0, and the x-intercept is 0.
What is the solution of 4x 3y 12?
Linear Equations in Two Variables
We plot the points (3, 0) and (0, 4) on a graph paper and join the same by a ruler to get the line which is the graph of the equation 4x + 3y = 12. Three different solutions of the equation 4x + 3y = 12 from the graph are (0, 4), (3, 0) and (6, –4).
What is the slope-intercept form of 5x 3y 15? The correct slope-intercept form is y=53x+15 .
Is 2x 3y 12 a linear function?
Explanation: 2x+3y=12 is the standard form for a linear equation.
What is the slope of 8x 9y 72? Reorder −8 – 8 and 8×9 8 x 9 . Rewrite in slope-intercept form. Using the slope-intercept form, the slope is 89 .
What is the y-intercept of y 2x 10?
The x and y intercepts of y = 2x – 10 are as follows: x-intercept = (5,0) y-intercept = (0,-10)
What is the slope of the equation y =- 5x 2?
Algebra Examples
Using the slope-intercept form, the slope is 5 .
How is a slope undefined? The slope of a line is undefined if the line is vertical. If you think of slope as rise over run, then the line rises an infinite amount, or goes straight up, but does not run at all.
Is negative undefined? The slope of a line can be positive, negative, zero, or undefined. … because division by zero is an undefined operation. Vertical lines are symbolically represented by the equation, x = a where a is the x-intercept.
How do you know when a slope is undefined?
A line has an undefined slope when it is a vertical line. A vertical line has no horizontal distance to it which is needed to have a positive, negative, or zero slope. An example of the equation of a line with an undefined slope would be x=4 .
What is the YYY intercept of y =- 3x? Using the slope-intercept form, the y-intercept is 0 .
Is Y =- 3x a linear equation?
Y=3x is a simple linear equation. To graph a linear equation Y=3x means to draw a line in the 2-D plane. Notice that the intercept on y-axis is 0 meaning the line will pass through the origin and slope of line is 3.
How do I find slope and y-intercept?
What is the y-intercept of the line 3x − 2y − 6?
Solution: To find the y-intercept of 3x + 2y = -6, let x = 0. y = -3 The y-intercept is -3. The line crosses the y-axis at the point (0, -3).
