From what I've learned about slope, I know that parallel lines have the same slope, and perpendicular lines have slopes which are negative reciprocals (that is, which have opposite signs and which are flipped fractions of each other). $$ You can use the point-slope form or slope intercept form equation to convert it into the Standard Form: You should be aware we cant use the fractions or decimals as the coefficient of the x. The slope is m, and the intercept is -ma + b. Then c is the y-intercept of the equation. c is the y-intercept of the equation of the line. Putting the values in the equation of the line in Point Slope Form: This is the equation of the line in the Point-Slope Form: Now consider the slope of the line m is 6 and the y-intercept c is 8. Standard. This equation describes a horizontal line that crosses the vertical axis at y = b. Make sure that you are comfortable with these techniques. The more popular is the slope intercept form: The truth is that this is nothing else than a more precise point-slope form. It is the point where the line crosses the y axis. Sometimes, there is no particular context; they just want you to solve the equation for y. When you have 2 points on a line on a graph the slope is the change in y divided by the change in x. It means the coefficient of the x should be just positive: We can find the y-intercept when x=0, it is a point where the line crosses the y-axis. Explain. Set parameters a = 4, b = 4 and c = 0.
