If you mean: y = 4.2x-6.3 then it is a straight line equation with a positive slope of 4.2 and a y intercept of -6.3
Points: (1, 5) and (2, 7) Slope: 2 Equation: y = 2x+3
Suppose the equation of the line is y = mx + c where m and c need to be determined. The slope of the line = (difference in y-coordinates of the two given points)/(difference in x-coordinates of the two given points) = (-6 - 2)/(0 - 4) = -8/-4 = 2 So m = 2 ie the equation of the line becomes: y = 2x + c where c still needs to be determined. The point (0, -6) is on the line. That is, when x = 0, y = -6. Substituting in the equation, -6 = 2*0 + c so that c = -6 and the equation of the line is y = 2x - 6
It is an equation of a straight line.
Plug both points into the equation of a line, y =m*x + b and then solve the system of equations for m and b to get equation of the line through the points.
There are infinitely many points on the line defined by the given equation.
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
(4,2), (2,1),(-2,-1)
All points whose y-coordinate is twice its x-coordinate.
(1,2) (0,5) (-1,8) (2,-1) (-2,11) All of these are solutions to the given equation.
But it's not an equation because there is no equal sign and no points are given.
(-2, 11)(-3, 14)(2, -1)
This is an equation of a line. There are an infinite number of solutions which are all points on the line. It is a linear equation.
