Question

1. Explain how to find the x and y-intercepts for an equation in standard form. Provide an example. Be able to explain how you would graph this type of equation.

2. What is the slope-intercept form of the equation for a line? Give an example. What do the variables represent?

3. Re-write the equation of 6x + 3y = 12 into slope-intercept form. State a coordinate pair (x, y) that would fall on that line

4. Write an equation for a line that passes through the points (1, 2) and (11, 22). The form is your choice.

5. Explain the relationship of the slopes of parallel and perpendicular lines.

6. Given y < 4x – 6, explain how to graph this and decide whether or not (– 1, 5) is a solution to this inequality

Answer 1

To find the x-intercept, substitute 0 for y. To find the y-intercept, substitute 0 for x.

answer choice 3

Explanation:

Answer 2

say you had an equation y=5x+17 the 17 is the y intercept or where the line comes off the y-axis and the 5x is the slope or the rise over run 5/1 is the slope so going up from the y intercept would be 1 up and 5 over and thats how you would graph it.
