Answer:

The equation in point-slope form is y-6=2(x-4).

Step-by-step explanation:

We are given the slope and a coordinate pair of a line.

  • Slope: 2
  • Coordinate Pair (x, y): (4, 6)

Therefore, we can now label our coordinate pair and substitute our values into the formula. Our formula is:

\displaystyle y-y_1=m(x-x_1)

We can label our coordinate pairs with the (x_1, y_1) labeling method.

Therefore, since our two coordinates are:

  • x = 4
  • y = 6

We can label 4 as x₁ and 6 as y₁.

Then, we are able to determine <em>m</em>, or our slope.

  • m = 2

Now, let's set up our equation.

\displaystyle y - y_1 = m(x - x_1)\\\\y - 6 = 2(x - 4)\\\\y - 6 = 2x - 8\\\\y = 2x - 2

Therefore, our line is y = 2x - 2. However, the problem asks for it in point-slope form. So, this is exactly what we have in Step 2: y - 6 = 2(x - 4).

Lady_Fox [76]

Answer:

b) 50

Step-by-step explanation:

you can multiply all of the answers by .7 (70% converted into a decimal) to see which one matches 35 miles.

24.5(.7) = 17.15 INCORRECT

50(.7) = 35 CORRECT

59.5(.7) = 41.65 INCORRECT

200(.7) = 140 INCORRECT
