Slope-intercept equation

How do you find the slope intercept equation?

The equation for slope-intercept form is: y=mx+b In this form, m is the slope of the line and the b is the y-intercept.

How do you find the slope intercept form step by step?

Graphing a Linear Equation Using Slope Intercept Formy = mx + b.Graph the equation: y = 2x + 4.Slope = 2 or 2/1.Y-intercept = 4 or (0,4)Step 1: Plot the y-intercept on your graph. Step 2: From the y-intercept (0,4) use the slope to plot your next point.The slope is 2, so you will rise 2 (up) and run 1 (to the right).

What is the Y intercept formula?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

How do you write an equation given two points?

Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

What is standard form slope?

Standard form is another way to write slope-intercept form (as opposed to y=mx+b). It is written as Ax+By=C. You can also change slope-intercept form to standard form like this: Y=-3/2x+3. A, B, C are integers (positive or negative whole numbers) No fractions nor decimals in standard form.

What is the slope of y =- 4?

the equation describes a horizontal line with a y-intercept of -4. as the line is horizontal, the slope is 0. The slope is 0 and the y-intercept is -4.

What is the slope of y =- 5x 1?

Using the slope-intercept form, the slope is −5 .

What is the formula for a linear equation?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

What is the Y intercept of y =- 2x?

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

How do you find the Y intercept with 2 points?

Equation from 2 points using Slope Intercept FormCalculate the slope from 2 points.Substitute either point into the equation. You can use either (3,7) or (5,11)Solve for b, which is the y-intercept of the line.Substitute b, -1, into the equation from step 2.
