A line passes through the points (1, –6) and (4, 3). A coordinate plane. What is the y-intercept of this line? –9 –3 3 9

-9

Step-by-step explanation:

eq.of line is

y+6=(3+6)/(4-1) ×(x-1)

y+6=3(x-1)

y+6=3x-3

y=3x-3-6

y=3x-9

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
