Question 256055: Given points (1,4) and (-3,0) write in standard form of a line

You can put this solution on YOUR website! Given points (1,4) and (-3,0) write in standard form of a line
.
First, determine the slope:
m = (y2-y1)/(x2-x1) = (4-0)/(1+3) = 4/4 = 1
.
Take one point (1,4) and the slope (1) and plug it into the "point-slope" form:
y - y1 = m(x - x1)
y - 4 = 1(x - 1)
y - 4 = x - 1
y = x + 3 (this is the slope-intercept form)
.
Moving the x and y to one side produces the "standard form":
-x + y = 3
