If you wanna find out if 2 lines are parallel you should compare the slopes. Pick two points XY to find the slope. Then put it into the formula y2 minus y1 divided by x2 minus x1. Then calculate the slope of both lines, if they are the same then the lines are parallel.

Answer:

To figure out if 2 lines are parallel, compare their slopes. You can find the slope of a line by picking 2 points with XY coordinates, then put those coordinates into the formula Y2 minus Y1 divided by X2 minus X1. Calculate the slope of both lines. If they are the same, then the lines are parallel.

You can find the slope of a line by picking 2 points with XY coordinates, then put those coordinates into the formula Y2 minus Y1 divided by X2 minus X1. Calculate the slope of both lines.

A plane travels 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind. when a tailwind is present, the plane
Nina [5.8K]

The meaning of the y-intercept exists in the time required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind.  $2 \frac{2}{9}$ hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.

<h3>What is the meaning of the y-intercept for the function$t(x)=\frac{2,000}{900}+x $$?</h3>

The time it takes the plane to travel 2,000 kilometers with the tailwind, t(x), exists determined by the function

$t(x)=\frac{2,000}{900}+x $$

where x exists the increase in speed when the plane travels with the wind (tailwind).

The y-intercept exists at x=0, then

$&t(0)=\frac{2,000}{900}+x \\

$&t(0)=\frac{20}{9}=2 \frac{2}{9} hours

$2 \frac{2}{9}$ hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.
