Find the x-intercept for the linear equation: 4x – 3y = 12 A) (0, -4) B) (0, 3) C) (-4, 0) D) (3, 0) i must be doing something wrong because i keep getting D as my answer and its A according to the answer key . can someone help me step by step?
4x-3y=12 -4x -4x -3y=-4x+12 /-3 /-3 /-3 y=-4/3x-4
4x-3(-4/3x-4)=12 4x-4x-4=12 +4 +4 0=8 x=0
this means that your final answer is a because it is -4 and 0
no sorry i dont get it. @ jamiero4ev3r
first i solved for y, then i solved for x
so i have to solve both?
@Jamierox4ev3r
To find the y-intercept point, substitute 0 for the OTHER letter, x. and solve for the remaining letter y. Then make an ordered pair, putting that for the y-coordinate, and 0 for the x-coordinate.
Yes, you need to solve for both
