The point slope form of a line is: y - y1 = m (x - x1) m is the slope and (x1, y1) is a point on the line This lesson will use the slope and a point that are given to write the equation of a line in this form

Find slope of a straight line? Formula : `y - y_A = m(x - x_A)` Solution : y - 4 = 8 (x - 5) y - 4 = 8x - 40 y = 8x - 40 + 4 y = 8x - 36 8x - y - 36 = 0Point slope form calculator uses coordinates of a point `A(x_A,y_A) `and slope m in the ...
The "point-slope" form of the equation of a straight line is:y − y1 = m(x − x1)The equation is useful when we know:one point on the line: (x1, y1) and the slope of the line: m,and want to find other points on the line.Have a play with it (move the point, try ...
Substituteslopefor 'm' and the coordinates forx1andy1into theformula. y − y1= m(x − x1) y − 5 = 3(x − -2) y − 5 = 3(x + 2) Yes, it really is that easy to write the equation of a line in point slope form when you knowits slopeand 1 point on the line!
Write the point-slope form of an equation of a line with a slope of 3 that passes through the point (6,−1)(6,−1). Then rewrite it in the slope-intercept form. Solution Let’s figure out what we know from the given information. The slope is 3, so m = 3. We also k...
