y=3x
y=13x
Both straight line equations will have the same slope or gradient but the y intercepts wll be different
The general equation of a line isy = mx + cIf the gradient is 3 then m = 3 so thaty = 3x + cSince the point (4,1) lies on this line, these coordinates must satisfy the equation.So 1 = 3*4 + cie c = -11Therefore, the equation is y = 3x - 11
The gradient of the line y = -3 is 0. So any parallel line has the equation y = c.Since it goes though the point (2, 6), c = 6 and so the equation is y = 6.
Intersection
y = -4x
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
If it passes through the origin
y = 3x
It is: y = -2x
y = 0. You can get this from the slope-intercept equation of the line.
The straight line equation is: y = 2x
y = - 3x
y = x
It is a straight line equation in the form of: y = x
y=13x
