How do you find the slope intercept form with slope and a point?

How do you find the slope intercept form with slope and a point?

The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.

What is the equation of the line that passes through the point − 2 7 and has a slope of − 2?

y = 2x
Answer: The slope-intercept form equation of the line that passes through the point (2, 7) and has a slope of 2 is y = 2x + 3.

What is the Y intercept of the slope is 2 3?

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the y-intercept is 23 .

What is the equation in point slope form of the line that passes through the point 1 24 and has a slope of?

y – y1 = m(x-x1) That is the equation of the line in point-slope form.

How do you find slope-intercept form from two points?

Steps to find the equation of a line from two points:

  1. Find the slope using the slope formula.
  2. Use the slope and one of the points to solve for the y-intercept (b).
  3. 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.

How do you write the equation of a line in slope-intercept form?

The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It’s usually easy to graph a line using y=mx+b.

What is the slope of 2 and 3?

Using the slope-intercept form, the slope is 0 .

What is y-intercept 3?

A y-intercept of 3 means that a line’s graph intersects the Y-axis at the point (0, 3). A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0, -4).

When to use slope intercept form in equation?

The slope intercept form is probably the most frequently used way to express equation of a line. To be able to use slope intercept form, all that you need to be able to do is 1) find the slope of a line and 2) find the y-intercept of a line. Video Tutorial on Slope Intercept Form

How to calculate the slope of a line?

The slope m of the line through any two points (x 1, y 1) and (x 2, y 2) is given by: The y-intercept b of the line is the value of y at the point where the line crosses the y axis.

How to find the y intercept of a line?

The y-intercept b of the line is the value of y at the point where the line crosses the y axis. Since for point (x 1, y 1) we have y 1 = m x 1 + b, the y-intercept b can be calculated by: How to use this calculator?

Is the slope of a vertical line undefined?

Vertical Lines. Since a vertical line goes straight up and down, its slope is undefined. Also, the x value of every point on a vertical line is the same. Therefore, whatever the x value is, is also the value of ‘b’.
