Question

Graph the line with slope -1/3 passing through the point (4,-2)

Answer 1

Y = mx + b
slope(m) = -1/3
(4,-2)...x = 4 and y = -2
sub and find b, the y int
-2 = -1/3(4) + b
-2 = -4/3 + b
-2 + 4/3 = b
-6/3 + 4/3 = b
-2/3 = b

so ur equation is : y = -1/3x - 2/3....or x + 3y = -2

ur y int is (0,-2/3)....ur x int is (-2,0)...ur slope is -2/3....other points on ur line include (1,-1) , (4,-2) , (7,-3), (10,-4), (-5,1), (-8,2)...plot these points...u should be able to see ur line from this
