Y = -4x - 5.....(0,?)...so we know x = 0, so sub in 0 for x and solve for y y = -4(0) - 5 y = -5....so one point is (0,-5) do the same for the other points and u get (1,-9) , (-1,-1)
y = -4x - 5.....slope is -4 and ur y int (where ur line crosses the y axes) is (0,-5). to find the x int (where the line crosses the x axes), sub in 0 for y and solve for x. 0 = -4x - 5 4x = -5 x = -5/4.....or - 1 1/4(for graphing purposes)...x int is (-5/4,0) so plot all ur points and connect the dots ============================ 4x + 9y = 0...(-9,?)..so x = -9..so sub in -9 for x and solve for y 4(-9) + 9y = 0 -36 + 9y = 0 9y = 36 y = 36/9 y = 4...so ur point is (-9,4)
do the same for the others and ur points are : (0,0) , (9,-4)
4x + 9y = 0 9y = -4x....so ur slope is -4 and ur y int is (0,0) ur x int is : (0,0)....so basically u have a line going through the origin (0,0) plot all ur points and connect the dots
