To find the equation of a line when given two points on the line, we first find the slope and then find they-intercept. Theslopeis the ratio of the change in the y-value over the change in the x-value. Given any two points on a line, you can calculate the slope of the line by...

A straight line is a one-dimensional figure. An infinite number of lines can pass through a single point, but there is only one unique line that passes through two points. Equation of a Straight Line An equation of a straight line is alinear equation. A straight line on a cartesian plane...
Show that the y-coordinates of the points of intersection of the line and the curve x^2+y^2-8y=9satisfy the equation 0y^2+(6k-8)y+(k^2-9)=0 .[1 Hence determine the exact range of values of k for which the line intersects the curve. ...
The equation of a straight line is usually written this way: (or y = mx + c in the UK see below) y = how far up x = how far along b = value of y when x=0
To find the missingb, use one of the two points. If a point is "on" a line, it makes the equation of the line true. Let's use (4,6) since positive values are easier. Remember (4,6) = (x,y). Plug into the equation forxandy. ...

Well, if I have two points on a straight line, I can always find the slope; that's what theslope formulais for. Now I have the slope and two points. I know I can find the equation (by solving first for "b") if I have a point and the slope; that's what I did in the prev...
2. What does the Equation of a Straight Line actually mean?The equation of a straight line is just a way of writing the relationship between the x co-ordinates and the y co-ordinates that lie on that line. 相关知识点: 试题来源: ...
