How do you simplify the expression $$5(3x - 8)$$ ?

The simplified form is $$15x - 40$$ .

What is the formula for finding the x-intercept of a linear equation?

To find the x-intercept, set $$y = 0$$ and solve for $$x$$ .

What is the slope of the line represented by the equation $$y = -8x + 13$$ ?

The slope of the line is $$-8$$ .

What is the point-slope equation for a line with slope 3 passing through the point (2, -1)?

The point-slope equation is $$y + 1 = 3(x - 2)$$ .

How do you find the y-intercept from the equation $$4x + 2y = 8$$ ?

Set $$x = 0$$ and solve for $$y$$ to find the y-intercept, which is $$(0, 4)$$ .

What is the equivalent equation for $$y + 3 = -8(x - 2)$$ ?

The equivalent equation is $$y = -8x + 13$$ .

What is the definition of a linear equation?

A linear equation is an equation that represents a straight line in a coordinate plane, typically in the form $$y = mx + b$$ .

What does the term 'slope' represent in a linear equation?

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

How do you determine if a point lies on a line represented by an equation?

Substitute the x and y coordinates of the point into the equation. If the equation holds true, the point lies on the line.
