You can put this solution on YOUR website! find the equation of straight line in the standard form.
gradient = -3 ,, graph passing through (5,1)
.
gradient is the slope
standard form is: Ax + By = C
.
Plug the given info into the "point-slope" form:
y - y1 = m(x - x1)
y - 1 = -3(x - 5)
y - 1 = -3x + 15
y = -3x + 16
3x + y = 16 (this is what they're looking for)
