Hi there!

\large\boxed{D. \text{ }y = -4x + 6}

To derive an equation given the points, we can use the slope formula:

slope = \frac{y_{2}-y_{1}}{x_{2}-x{1}}

Plug in the corresponding coordinates:

slope = \frac{-6-2}{3-1}

Simplify:

slope = \frac{-8}{2} = -4

Therefore, we have:

y = -4x + b

Plug in the x and y values for a coordinate to solve for b:

2 = -4(1) + b

2 = -4 + b

b = 6

The equation is:

y = -4x + 6. The correct answer is D.

Need help on this please this one is hard for me

Answer:

  y = -7x

Step-by-step explanation:

The line goes through the origin, so the y-intercept is b=0.

The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...

  m = rise/run = -7/1 = -7

Then the slope-intercept form equation is ...

  y = mx + b

  y = -7x

Answer:

325 miles

Step-by-step explanation:

Given that,

A car travels 390 miles in 6 hours.

We need to find the distance travelled in 5 hours.

6 hours = 390 miles

1 hour = 65 miles

In 5 hours,

5 hours = (65×5) miles

= 325 miles

So, it will travel 325 miles in 5 hours.
