Question

I don't understand Graphing Linear Equations

Answer 1

Answer:

Khan Academy does a great job explaining in their videos titled Graphing Linear Equations. They also offer pracice with explinations and quizez on it.

Step-by-step explanation:

Answer 2

Answer: The equation for a line is y = mx + b. B is the y-intercept (where x=0). If your B value is 6, then your y-intercept is (0,6). This is the same with negatives, if you have a negative B value, then the y-intercept is below the x-axis. For example, a B value of -6 would mean that the line crosses the y-axis at (0,-6).

M is your slope. Your slope can be determined by rise/run (how far your line goes up between each point/how far horizontally your line travels between each point). A slope of 2 would mean that the y-values on my line are double the x-values on my line. If a point on the line was (1,2), we could find the slope value by taking 2 and dividing it by 1.

If I had y = 6x+2, my slope would be 6, and my y-intercept would be 2.

Feel free to ask anything is still a little confusing :D
