STANDARD FORM:

y = mx + b, where m is slope and b is y-intercept.

ANSWER:

First we will find the slope and then y-intercept.

slope(m) = y2 - y1/x2 - x1

  • 9 - 1/- 6 - 4
  • - 8/10
  • - 4/5.

Now, 1 = - 4/5 × 4 + b

1 = - 16/5 + b

b = 1 + 16/5

b = 5 + 16/5

b = 21/5.

So, equation becomes

  • y = - 4/5x + 21/5.

Answer:

<u>Find the slope:</u>

  • m = \frac{y2-y1}{x2-x1} = \frac{9 - 1}{-6 - 4} = -\frac{8}{10} = -\frac{4}{5}

<u>Use point-slope form and one of the points:</u>

  • y - y₁ = m(x - x₁)
  • y - 1 = -\frac{4}{5}(x - 4)

16x 2 + 8x - 15 Mathematics?
Gala2k [10]
If you're factoring, your answer is

(4x - 3)(4x + 5)

You'll work it out this way:

16x^2 + 8x - 15

Since there's no GCF here, you multiply the first and third terms, giving you -240. Your next step is to find two numbers that have a sum of 8 and a product of -240. These numbers are 20 and -12. Plug those in and you've got:

16x^2 + 20x - 12x - 15

From here you divide it into two binomials. These are (16x^2 + 20x) and (-12x - 15).
When you take out the greatest common factors (4x and -3), they become:

4x(4x + 5) - 3(4x + 5)

Then you group what's outside of the parentheses together (4x - 3)
And bring what's inside of the parentheses down (4x + 5).
This brings your answer to

(4x - 3)(4x + 5)
