Graph the line through point (1,1) with slope 2.
Luba_88 [7]

Step-by-step explanation:

The equation of a line is y=mx+b, where m is the slope and b is the y intercept.

We know that the line pass through the point (1,1) and the slope is 2.

m=2

Then,

y=2x+b

We have to find b.

If we replace the point (1,1) in y=2x+b we will obtain b.

Then,

y=2x+b\\1=2.1+b\\1=2+b\\1-2=b\\-1=b

y=2x-1

The y intercept then is -1, this means that when x=0, y=-1.

We have the point (0,-1).

Now to obtain another point we have to replace  y=2x-1 with y=0.

y=2x-1\\0=2x-1\\1=2x\\\frac{1}{2}=x

We have the point (\frac{1}{2},0)=(0.5,0)

Now that we have to points, we have to place them in the cartesian coordinate system. And then draw the line.

A two-digit number is 5 times the sum of its digits. If 9 is added to the number, its digits are reversed. Find the number​
forsale [732]

Answer:

The number = 45

Step-by-step explanation:

Let the 10s digit = x

Let the units digit = y

10*x + y = 5(x + y)                        Start here: remove the brackets

10*x + y + 9 = 10y + x                   Subtract y and 10x from both sides

Using the first equation

10x + y = 5x + 5y

5x + y - 5y = 0

5x - 4y = 0

5x = 4y

y = 5/4x

From the second equation

9 = 9y - 9x

1 = y - x           Substitute y = 5/4 x

1 = 5/4x - x

1 = 1/4  x

x = 4

y = 5/4 * 4

y = 5.
