We can now put the two pieces together (gradient and y - intercept) to find the equation of any line.
The formula is y = mx +c, where m is gradient and c is the y - interecpet.
Look at the examples below to help you.
The formula is y = mx +c, where m is gradient and c is the y - interecpet.
Look at the examples below to help you.
Finding the equation of a line: y = mx + c
The gradient of the line is -3/2
Therefore m = -3/2
The y-interecept is 3
Therefore c = 3
The equation is y = mx +c
so y = -3/2x + 3
Therefore m = -3/2
The y-interecept is 3
Therefore c = 3
The equation is y = mx +c
so y = -3/2x + 3
The gradient of the line is 1/1 = 1
Therefore m = 1
The y-interecept is 1
Therefore c = 1
The equation is y = mx +c
so y = 1x + 1
Therefore m = 1
The y-interecept is 1
Therefore c = 1
The equation is y = mx +c
so y = 1x + 1
