Writing and Graphing Linear Equations from Tables

What is the slope-intercept form of a linear equation?

• y = mx + b

• y = ax + b

• y = a/x + b

• y = ax^2 + bx + c

Why is it important to use multiple points in a table to find the slope?

• To ensure the slope is positive

• To accurately identify the constant rate of change

• To find the y-intercept

• To make the graph look better

What is the first difference in a table?

• The difference in x values

• The difference in y values when x values are evenly spaced

• The product of x and y values

• The sum of x and y values

How do you determine the y-intercept from a table?

• By finding where the x value is 1

• By finding where the x value is 0

• By calculating the average of y values

• By using the slope formula

What is the equation of a line with a slope of -2 and a y-intercept of 6?

• y = -6x + 2

• y = 2x - 6

• y = 6x - 2

• y = -2x + 6

How can you find the slope when x values are not evenly spaced?

• By using the slope formula

• By using the first difference

• By averaging the y values

• By finding the midpoint of x values

What does it mean if a point does not satisfy the linear equation?

• The point is part of the linear relationship

• The point is not part of the linear relationship

• The equation is incorrect

• The graph is incorrect
