Answer:

<h2>         y - 2 = -3(x - 1)</h2>

Step-by-step explanation:

The point-slope form of the equation that describes the line with a slope of <em>m</em> that contains the point (x₀, y₀) is: y - y₀ = m(x - x₀)

m = - 3

(1, 2)  ⇒    x₀ = 1,  y₀ = 2

Therefore:

y - 2 = -3(x - 1)

If a line includes the points (8,0) and (20,12). What is its equation in slope-intercept form?
aev [14]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

substitute the coordinates of the points (8, 0) and (20, 12) to the formula:

m=\dfrac{12-0}{20-8}=\dfrac{12}{12}=1

y = 1x + b = x + b

Put the coordinates of the point (8, 0) to the equation of a line:

0 = 8 + b      <em>subtract 8 from both sides</em>

-8 = b

<h3>Answer: y = x - 8</h3>

If you reduce a twelve times a number by 40, you get the same number as if you increase its seven times by 25. What number is th
Digiron [165]

Step-by-step explanation:

Take the number as x

12x-40=7x+25

collect like terms

12x-7x=25+40

5x=65(divide both sides by 5)

x=13

Therefore number is 13
