Converting Slope-Intercept Form to Standard Form - Algebra I

In this video, you will learn how to convert slope-intercept form equations to standard form equations. A slope-intercept form equation is any linear equation in the form of y=mx+b, in which the m is the slope and b is the y-intercept. In order to convert a slope-intercept form equation to a standard form equation, it's important to know that the standard form of any linear equation is ax+by=c, in which a and b are coefficients and c is the constant. The first step is to identify the x and y values. In slope-intercept form, the y is on the left hand side of the equation, whereas the x is on the right hand side. In standard form, the x and y values must be on the left hand side, so you will subtract the x value in y=mx+b onto the left hand side. Next, you must rearrange terms to get them into ax+by=c form.

Zero and Negative Exponents - Algebra I

In this video, you will learn about zero and negative exponents. There are many properties of exponents, including the zero exponent property and the negative exponent property. The zero exponent property states that any number to the power of 0 is always 1. That means that if the exponent is 0, the solution is always going to be 1, no matter how small or large the number is. The negative exponent property states that whenever a number has a negative exponent, you will multiply that number by itself that many times, but when you get your answer, it will be a fraction of 1/(the answer). For example, 2^---2 = 4 = 1/4. For more steps, watch the video and don't forget to like and subscribe!
