Answer:
Part 1) [tex]x-2y=2[/tex] ----> (2,0) and (0,-1)
Part 2) [tex]-3x+3y=7[/tex] ----> (-7/3,0) and (0,7/3)
Part 3) [tex]7x-y=21[/tex] ----> (3,0) and (0,-21)
Part 4) [tex]3x-5y=-20[/tex] ----> (-20/3,0) and (0,4)
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
The x-intercept is the value of x when the value of y is equal to zero
Part 1) we have
[tex]x-2y=2[/tex]
1) Find the x-intercept
For y=0
[tex]x-2(0)=2\\x=2[/tex]
the x-intercept is (2,0)
2) Find the y-intercept
For x=0
[tex]0-2y=2\\y=-1[/tex]
the y-intercept is (0,-1)
Part 2) we have
[tex]-3x+3y=7[/tex]
1) Find the x-intercept
For y=0
[tex]-3x+3(0)=7\\x=-\frac{7}{3}[/tex]
the x-intercept is (-7/3,0)
2) Find the y-intercept
For x=0
[tex]-3(0)+3y=7\\y=\frac{7}{3}[/tex]
the y-intercept is (0,7/3)
Part 3) we have
[tex]7x-y=21[/tex]
1) Find the x-intercept
For y=0
[tex]7x-(0)=21\\x=3[/tex]
the x-intercept is (3,0)
2) Find the y-intercept
For x=0
[tex]7(0)-y=21\\y=-21[/tex]
the y-intercept is (0,-21)
Part 4) we have
[tex]3x-5y=-20[/tex]
1) Find the x-intercept
For y=0
[tex]3x-5(0)=-20\\x=-\frac{20}{3}[/tex]
the x-intercept is (-20/3,0)
2) Find the y-intercept
For x=0
[tex]3(0)-5y=-20\\y=4[/tex]
the y-intercept is (0,4)
Answer:
Part 1) ----> (2,0) and (0,-1)
