Equations of Linear Functions Quick check

Answer 1

1. What is the general form of the equation of a linear function?

The general form of the equation of a linear function is y = mx + b, where m is the slope of the line and b is the y-intercept.

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

The slope-intercept form of the equation of a linear function is y = mx + b, where m is the slope of the line and b is the y-intercept.

3. What is the point-slope form of the equation of a linear function?

The point-slope form of the equation of a linear function is y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line.

4. How do you find the slope of a line given the coordinates of two points on the line?

To find the slope of a line given two points (x1, y1) and (x2, y2), you can use the formula m = (y2 - y1) / (x2 - x1).

5. How do you find the y-intercept of a linear function?

To find the y-intercept of a linear function, you can set x = 0 in the equation of the line and solve for y. The y-intercept is the y-coordinate of the point where the line intersects the y-axis.
