What is the slope of the line described by the equation below?
Equation of a straight line is: y = mx+c whereas m is the slope and c is the y intercept
How can you find an equation line between two pair of points?
Assuming you want the equation of the straight line between the two points (x0, y0) and (x1, y1), the equation is: y - y0 = m(x - x0) where m is the gradient between the two points: m = (y1 - y0) ÷ (x1 - x0) Note: if the two x coordinates are equal, that is x0 = x1, then the equation of the line is x = x0.
What is the point-slope formula and how is it used?
Given a straight line with slope m and a point (p,q) on the line, the point-slope formula of the line is (y - q) = m(x - p) It is used to represent a straight line in the Cartesian plane. This allows techniques of algebra to be used in solving problems in geometry.
In the equation for a straight line y equals mx plus b what is the x-intercept equal to?
The x-intercept is equal to -b/m.
Why do they use m and b in a linear equation?
The equation for a straight line is y = mx+b whereas m is the slope and b is the y intercept For example: y = 3x+9 which means that 3 is the slope and 9 is the y intercept
