Write an equation of the line that passes through (-5, -2) and is parallel to y=2/3x+1<br><br> y=?
Nutka1998 [239]

Answer:

<h2>          y = ²/₃x + ⁴/₃</h2>

Step-by-step explanation:

The point-slope form of the equation of line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

y = 2/3x + 1   ⇒    m₁ = 2/3    ⇒    m₂ = 2/3

(-5, -2)    ⇒    x₁ = -5,  y₁ = -2

point-slope form:

y - (-2) = 2/3(x - (-5))

y + 2 = 2/3(x + 5)

y + 2 = 2/3x + 10/3               {subtact 2 from both sides}

y = 2/3x + 4/3         ←   slope-intercept form

The circumference of F is 120 cm what is the length of DE the minor arc
AfilCa [17]

Answer:

Option E 15 cm

Step-by-step explanation:

we know that

The circumference of a circle subtends a central angle of 360 degrees

so

using proportion

Find out the length of arc DE by a central angle of 45 degrees

Let

x -----> the length of arc DE

\frac{120}{360}=\frac{x}{45}\\\\x=120*45/360\\\\x=15\ cm

What is the pattern of the trend line equation in this graph?
kondaur [170]

The pattern of the trend line from what we can see here shows the existence of a positive upward trend.

<h3>What is a positive upward trend?</h3>

We can see that the graph has fluctuations which have an upward trend over the years. This upward trend can be gotten from the straight line that was drawn on the graph.

It slants to the top. This shows us that the trend is positive and rising over the period of time that we have in the graph. In the graph, the upward trend can be seen from the fact that there has been a rise in the temperature of the city over the time period that was illustrated. The increase in temperature rose from 31.5 to 33 degrees period of time.

Hence we can conclude that The pattern of the trend line from what we can see here shows the existence of a positive upward trend.
