Find the equation of the line.<br> Use exact numbers.

Grace [21]

The equation would be y=2/3x+4

So to finish the equation, you would need the slope and the y-intercept. The y-intercept is where the line hits the y-axis. So it hits the y-axis at (0,4), making the y-intercept 4.

Next find the slope. Do this by picking two points and plugging it into the equation

y2-y1/x2-x1

(0,4) (3,6)

6-4/3-0

2/3

So it would be y=2/3x+4

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

width-to -height ratio of 16:9

Let analyse all possible answers:

4 feet by 3 feet

28 inches by 21 inches

16 divided by 28 is different as 9 divided by 21 => it is wrong

48 centimeters by 27 centimeters

16 divided by 48 is different as 9 divided by 27 => it is wrong

26 inches by 19 inches

16 divided by 26 is different as 9 divided by 219=> it is wrong

We choose A.

Hope it will find you well.
