How do you find the equation of a line from a line?
Steps to find the equation of a line from two points:
- Find the slope using the slope formula.
- Use the slope and one of the points to solve for the y-intercept (b).
- Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
What is the equation of a vertical line passing through − 5 − 2?
x = -5
Summary: The equation of a vertical line passing through (-5, -2) is x = -5.
How do you find the equation of a line in slope intercept form?
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept.
What is the equation of the horizontal line through (- 4 6?
In a horizontal line the y value remains the same. In the point ( -4. -6 ) the y value is -6. the point notation is always written as ( x, y).
What is the equation of a line through the points (- 1/3 and 2/3 )?
Answer: The equation of a line passing through the points (-1, 3) and (2, -3) is 2x +y = + 1.
How do you write an equation answer?

| A number divided by six is eight. |
What is the equation of the vertical line through (- 8 5?
A vertical line has a constant x coordinate. Since the line is going through (-8,5), whose x coordinate is -8, the equation of the line is x = -8.
How do you find the equation of a line with slope and a point?
These are the two methods to finding the equation of a line when given a point and the slope: Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. Use the m given in the problem, and the b that was just solved for, to create the equation y = mx + b.
What is the equation of the vertical line through (- 5 2?
What is the equation of the line goes through (- 1 3?
The slope-intercept form equation of the line that passes through (1, 3) and (3, 7) is y = 2x +1.
