Find the Quetion of the line that passes through the points (1,6) and (5,2)
NemiM [27]

Answer:

y=-x+7

Step-by-step explanation:

Equation of straight line is given as

y-y_1=m(x-x_1)

where slope m is calculated as

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

<u>Here </u>

(x_1, y_1)=(1, 6) \ \ and \ \ (x_21, y_2) = (5, 2)

m = \frac{2 - 6}{5 - 1}\\m=\frac{- 4}{4} \\m=-1

<u>Equation of line that passes through the points (1,6) and (5,2)</u>

<u />y-6=-1(x-1)\\y=-x+7<u />

Jen says that the solutions of the inequality -2(3 – x) &gt; 2x – 6 are all real numbers. Do you agree with your friend? Explain
Maslowich

Answer:

I disagree

'No it won;t

Step-by-step explanation:

Given the inequality functions;

-2(3 – x) > 2x – 6

Open the parenthesis

-2(3) -2(-x)  > 2x - 6

-6 + 2x > 2x - 6

Collect like terms

2x-2x > -6 + 6

0x > 0

x > 0/0

<em>The value of x does not exist on any real number. I disagree with my friend since the value of x is an indeterminate function. If the inequality were ≥, it won't change anything as the value of x won't still exist on any real number </em>

H. Goes through (-3, -2) and parallel to y = 5 x +5
olchik [2.2K]

Answer:  y = 5x + 13

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

Parallel means it has the same slope.  

Given line y = 5x + 5  --> the slope is 5, so parallel slope is 5

Use the Point-Slope formula: y - y₁ = m(x - x₁)  such that

  • m = 5
  • (x₁, y₁) = (-3, -2)

y + 2 = 5(x + 3)          <em>input m and (x₁, y₁) into the Point-Slope formula</em>

y + 2 = 5x + 15          <em>distributed</em>

     y = 5x + 13          <em>subtracted 2 from both sides</em>
