Use the point-slope form to find a general form of the equation of the line whose slope is (-1/4) and that passes through (-2,3).
:
The point/slope formula: y - y1 = m(x -x1)
:
In your problem: m = -1/4; x1 = -2; y1 = 3
;
y - 3 = (-1/4)(x - (-2))
:
y - 3 = (-1/4)(x + 2)
:
y - 3 = -(1/4)x - 2/4
:
y - 3 = -(1/4)x - (1/2)
:
y = -(1/4)x - (1/2) + 3
:
y =
:
y =
:
You can also write it in the decimal form:
y = -.25x + 2.5
