That will depend on the value of the slope which has not been given.
The general equation of the line is y = 3x + c. Having only one coordinate (21) of a point on this line is not enough to evaluate c.
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).
Given a point P(a,b) and slope m, the point slope equation is (y - b)/(x - a) = m
point of intersection
If you mean a point of: (2,1) then the equation works out as y = 3x-5
If you mean points of (-1, 9) and (5, 21) then the slope works out as 2
The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
That will depend on the value of the slope which has not been given.
The slope of a line and the perpendicular to that line, when multiplied together, give -1. So, if the first line has a slope of 1/21, the second has a slope of -21.
If you mean points of (-1, 9) and (5, 21) then the slope of the line works out as 2
The general equation of the line is y = 3x + c. Having only one coordinate (21) of a point on this line is not enough to evaluate c.
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.
no it is different
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).
Given a point P(a,b) and slope m, the point slope equation is (y - b)/(x - a) = m
