3 things you must know before graphing linear equations

What is the first step in solving for Y in a linear equation?

• Add all terms to one side

• Multiply all terms by a constant

• Square both sides of the equation

• Undo addition or subtraction

When converting an equation to slope-intercept form, what should you do after isolating Y?

• Add a constant to both sides

• Divide each term by the coefficient of Y

• Multiply each term by the coefficient of X

• Subtract the X term from both sides

What does the first number in a coordinate point represent?

• The slope of the line

• The Y coordinate

• The distance from the origin

• The X coordinate

How do you determine the position of a point on the Y-axis?

• By its X coordinate

• By the sum of its coordinates

• By its Y coordinate

• By the product of its coordinates

What does it mean for a point to satisfy a linear equation?

• The point lies on the X-axis

• The point makes the equation true when substituted

• The point is at the origin

• The point has equal X and Y values

What should you do to check if a point satisfies a linear equation?

• Multiply the point's coordinates

• Add the point's coordinates together

• Substitute the point's coordinates into the equation

• Graph the point and see if it lies on the line

Why is it helpful to use parentheses when substituting values into an equation?

• To simplify the equation

• To avoid mistakes with negative values

• To make the equation look neater

• To ensure the equation is balanced
