WRITE AN EQUATION OF THE LINE IN SLOPE-INTERCEPT FORM.
The line with slope -2 and passing through (3,1).
+5478 Slope: -2
Point: (3,1)
Slope-intercept form: y = mx+b
First use the point-slope formula: (y-y1) = m(x-x1) where (x1,y1) are the coordinates of the point and m = slope.
So:
y-1 = -2(x - 3)
Multiply out the -2.
y - 1 = -2x + 6
Add 1 to both sides.
y = -2x + 7
