what would the slope equation be. Slope y₂ - y₁ x₂ - x₁ Notice that the slope of a line is easily calculated by hand using small whole number coordinates. This form is quite useful in creating an equation of a line if youre given the slope and a point on the line.

Whats Point-Slope Form of a Linear Equation. The only ones that cant be changed into slope-intercept form are the equations of vertical lines which look like x a number Once your equation is in slope-intercept form. The slope is m or the coefficient of x in the equation.
M y 2 y 1 x 2 x 1 It is important to keep the x-and y-coordinates in the same order in both the numerator and the denominator otherwise you will get the wrong slope.
You may already be familiar with the ymxb form called the slope-intercept form of the equation of a line. Its kind of annoying to have to draw a graph every time we want to find the slope of a line isnt it. The slope formula uses two points x1 y1 and x2 y2 to calculate the change in y over the change in x. The only ones that cant be changed into slope-intercept form are the equations of vertical lines which look like x a number Once your equation is in slope-intercept form.
