The point slope form of a line is the equation
y-y_1=m*(x-x_1)
where y_1 and x_1 are coordinate for some point the line intersect and m is the slope. Just plugging in your given numbers gives the equation
y+4=-2*(x+8)
It is: y = 5x+6
Point-slope form: y - y1 = m(x - x1) y+6=-1/8(x+4)
You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
The equation of a line passing through a point P with coordinates (a,b) and slope m is (y-b) = m(x-a) changing that to the more conventional form: y = mx + (b - ma)
Point-slope form is written as: y-y1=m(x-x1), where (x1, y1) is a point on the line and m is the slope (hence the name, point-slope form).
Point slope form is standard form. To change point slope form into general form, simply multiply both sides by the denominator of the slope, and move everything onto one side.
no it is different
It is: y = -31 and there is no x intercept or slope
point slope form is y-y1=m(x-x1). x1 and y1 are both points and m is the slope.
The slope of a vertical line is undefined and so there cannot be a slope-intercept form of the equation.
Point-slope form is just another way to express a linear equation. It uses two (any two points that fall on the line) and the slope of the line (Therefore the name point-slope form).y2 - y1 = m(x2 - x1)...with m as the slope.
Given a point P(a,b) and slope m, the point slope equation is (y - b)/(x - a) = m
