What is an equation in point-slope form for the line that passes through the points (-3,5) and (2, -3)?
zloy xaker [14]

Answer:

y - 5 = -8/7(x + 3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication

  6. Addition

  • Left to Right

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-3, 5)

Point (2, -3)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{-3-5}{2+5}
  2. Subtract/Add:                      m=\frac{-8}{7}

<u>Step 3: Write Equation</u>

<em>Plug in variables into the general form.</em>

y - 5 = -8/7(x + 3)

y + 3 = -8/7(x - 2)

The points (1, 5) and (0, –2) fall on a particular line. What is its equation in slope-intercept form?
Hunter-Best [27]

Answer:

y = 7x - 2

Step-by-step explanation:

first we need the slope of the line.

the slope is expressed a the ratio (y coordinate change / x coordinate change) when we go from one point on the line to another.

so, let's say we go from (0, -2) to (1, 5), we see

x changes by +1 (from 0 to 1).

y changes by +7 (from -2 to 5)

so the slope is +7/+1 = 7

the slope-intercept form is in general

y = ax + b

a being the slope, b being the y-intercept (the y-value for x = 0).

the point (0, -2) gives us therefore the y-intercept directly : -2.

by using the already established slope and the point (0, -2) for the y-intercept the equation of our line is

y = 7x - 2

how is the sentence "10 more than p is –3" written as an equation? – 3 = 10 p 10 = –3 p 10 = 3 p = 10 – 3
yarga [219]
This is saying that -3 is the result of a number "p" plus 10...therefore the equation is p+10=-3
