Find the value of b if the graph of the equation y=−3x+b goes through the given point.

b(5, 2)

b = 17

Step-by-step explanation:

Substitute the given coordinates x = 5 and y = 2 into y = mx + b and then solve the resulting equation for b:

2 = -3(5) + b, or

2 = -15 + b

Then b = 17, and the desired equation is y = -3x + 17.

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
