The straight line is given by the equation
y=kx+b
We substitute coordinates of points
3=2k+b (1)
9=4k+b (2)
We give a system of equations
Solution of this system
(1) 2k=3-b
k=(3-b)/2
(2) 9=2(3-b)+b
9=6-b
b=-3
k=3
Answer: y=3x-3
Answer:
x = 1 and y = 4
Step-by-step explanation:
Solution,
(x+2,y) = (3,4)
Now,
Comparing corresponding elements,
x+2 = 3 , y = 4
or, x = 3 - 2 , y = 4
or, x = 1 , y = 4
Therefore, the value of x is 1 and y is 4.
Answer:
Width: 32 inches
Step-by-step explanation:
First you wanna find the scale factor by dividing the new length over the old; 24/3=8. Now that we have the scale factor, we can multiply 4 by the scale factor to get 32 inches, which is your width.
