How do you find the formula for Y?

How do you find the formula for Y?

Review the slope-intercept form. You can describe a straight line with the formula y = mx + b, where m is the slope and b is the y-intercept. Now that we know the slope m and a point (x,y), we can use this equation to solve for b, the y-intercept.

How do you find the equation of a fraction?

Solving a Fractional Equation. An equation in which one or more terms is a fraction is called a fractional equation. To solve a fractional equation, first eliminate the fractions by multiplying both sides of the equation by the least common denominator (LCD) of every term.

How do you get a fraction out of the denominator?

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

How do you find y int with 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 simplify imaginary fractions?

To simplify this fraction we multiply the numerator and the denominator by the complex conjugate of the denominator. When we reverse the sign of the imaginary part, we have the complex conjugate. Another way to think of this is to replace all the i with -i. As we can see here, the complex conjugate of 3 – 4i is 3 + 4i.
