Thank you but could you explain how to do it because I have more problems like this and like i said i dont know what to do when there is a number with the y

Choice B is not the correct answer.
Jayshal is wrong.
so it says y-3=1\2(x+2) when u say substitute and solve for y do you mean this
Substitute in x = -10 and solve for y.
What choices can you eliminate from that?
ohh i see what you did thereSorry it's A
substitute a or b in the formula and to get final result you can move numbers to other side and change sign + to -
y-3=1/2(x+2)
y-3=1/2(-10+2)
y-3=-4
y-3(+3)=-4+3
y=1
do the rest of them like that
.y-3(+3)=-4+3 \(\displaystyle \ \ \ \ \ \)No parentheses! This would be the equivalent of the left-hand side equal to y - 3(3) = y - 9.
View attachment 4164 Okay so I used the method you said on this new problem
and I have narrowed it down to B or D but how do i figure the x value if I only know Y
No I dont could you show me pleasey + 2 = -4(x - 1)
Substitute 2 in for y and solve for x.
Do you know how to do that?
4 - 4 = -4x + 4 - 4 what did you do here? i dont understand past where you distributed.I will show you, but then I will leave this thread, and I won't make a promise to come back due to other obligations.
y + 2 = -4(x - 1)
Substitute in y = 2:
2 + 2 = -4(x - 1)
4 = -4(x - 1)
4 = -4x + 4
4 - 4 = -4x + 4 - 4
0 = -4x
0/(-4) = -4x/(-4)
0 = x
or
x = 0
Alternatively, at this point divide both sides by -4:I will show you, but then I will leave this thread, and I won't make a promise to come back due to other obligations.
y + 2 = -4(x - 1)
Substitute in y = 2:
2 + 2 = -4(x - 1)
4 = -4(x - 1)
4 = -4x + 4
4 - 4 = -4x + 4 - 4
0 = -4x
0/(-4) = -4x/(-4)
0 = x
or
x = 0
i finished the assignment
Ooohhh! I just never ends!:idea: Now it's time to go do some more homework.
