Find the equation of this line<br><br> y = [?]x + [ ] <br> Please help
larisa [96]
<h2>Writing an Equation of a Line in Slope-Intercept Form</h2><h3>Answer:</h3>

y = [ -2 ] x + [ 1 ]\\

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about Slope-Intercept Form: <u>brainly.com/question/24599351</u></em>

We must first find the slope.

<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>

  • <em><u>brainly.com/question/24640665</u></em>
  • <em><u>brainly.com/question/24638053</u></em>

We can see the marked points, (0,1) and (4, -7), are on the line.

Solving for the slope:

m = \frac{y_2 -y_1}{x_2 -x_1} \\ m = \frac{-7 -1}{4 -0} \\ m = \frac{-8}{4} \\ m = -2

Now we can now solve for the y-intercept.

<em>Please refer to the second paragraph of my Answer from this Question to know more about y-intercepts: <u>brainly.com/question/24606058</u></em>

We can see that the line intersected the y-axis at (0,1) so b = 1.

I can't figure out the x-intercepts. Help. NO LINKS
zavuch27 [327]

Answer:

(-3,0)

Step-by-step explanation:

To find the x-intercept set y to 0,

x^2 + 6x + 9 = 0     Now you have a quadratic equation, so you can solve it

(x + 3)(x + 3 ) = 0

x + 3 = 0

x = -3
