pending Learning Task 1: Find the x and y-intercepts of the following equations. Write your answer in your notebook. The first one is done for you. 1. x + y = 3 Ans. If x=0, then x + y = 3 0 + y = 3 If y = 0, then x + y = 3 x+0=3 x= 3 y = 3 2. 3x + 9 = y 3. X= y + 2 4. 4x + 2y = 6 5. x + 4y = 4 6. 9x + y =9 os pls taman sagot pls

Answer:
2.) 3x+9=y
if x=0 then
3x+9=y
3(0)+9=y
0+9=y
y=9
if y=0 then
3x+9=y
3x+9=0
3x=-9
3x/3=-9/3
x=-3
3.) x=y+2
if x=0 then
x=y+2
0=y+2
y=-2
if y=0 then
x=y+2
x=0+2
x=2
4.) 4x+2y=6
if x=0 then
4x+2y=6
4(0)+2y=6
0+2y=6
2y/2=6/2
y=3
if y=0 then
4x+2y=6
4x+2(0)=6
4x+0=6
4x/4=6/4
x=3/2 or 1.5
5.) x+4y=4
if x=0 then
x+4y=4
0+4y=4
4y/4=4/4
y=1
if y=0 then
x+4y=4
x+4(0)=4
x+0=4
x=4
6.) 9x+y=9
if x=0 then
9x+y=9
9(0)+y=9
0+y=9
y=9
if y=0 then
9x+y=9
9x +0=9
9x/9=9/9
x=1
