where b is the constant. (-1, 0) m = -2

y = mx + b
0 = (-2)(–1) + b
0 = 2 + b
-b = 2
b = -2

the equation of the line is
y = -2x - 2

Find the equation of a line with the given points. (Put your answers in the form y = mx + b.) (7, 2) (5, 4)
Weegy: you can follow these steps: Given 2 points example. Find the equation of the line thru the points (2,1) and (3,5) - - - - - - - - - - - This is a 2 step process. [ First find the slope of the line thru the points. slope, m = diffy/diffx m = (5-1)/(3-2) m = 4 - - - - - Now use y = mx + b with either point to find b, the y-intercept. y = mx + b 5 = 4*3 + b b = -7 - - - - y = mx + b y = 4x - 7 is the answer. - - - - - - - - - - - - Another approach using determinants: |x y 1| |2 1 1| = 0 |3 5 1| - - - - x(1-5) - y(2-3) + 1(10-3) = 0 -4x + y + 7 = 0 y = 4x - 7 ] (More)
