a line is paralll yo y=4x-2 and intersects the point (5,-11). what is the equation of this parallel line
victus00 [196]

The equation of line parallel to given line is: y=4x-31

Step-by-step explanation:

Given equation of line is:

y = 4x-2

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.

Let m1 be the slope of the given line

then

m1 = 4

Let m2 be the line that is parallel to given line

As we know that the slopes of parallel lines is equal so

m1=m2 = 4

The slope-intercept form of equation of line is:

y = m_2x+b

Putting the value of slope

y = 4x+b

to find the value of b, putting (5,-11) in the equation

-11 = 4(5) + b\\-11 = 20+b\\b = -11-20\\b = -31

Putting the value of b

y=4x-31

Hence,

The equation of line parallel to given line is: y=4x-31

Keywords: Equation of line, slope

Can someone plz help me with this one problem plz!!!
kondor19780726 [428]

Answer:

<h2><em><u>25 square inches </u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>, </u></em>

Parallel sides of the trapezium = 3in, 7in

Height of the trapezium = 5in

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the trapezium

=  \frac{1}{2}  \times sum \: of \: parallel \: sides \times height

=  \frac{1}{2}  \times (7 + 3)in \times 5in

=  \frac{1}{2}  \times 10in \times 5in

= 5in × 5in

=  {25in}^{2}

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Area</u></em><em><u> </u></em><em><u>if</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>trapezium</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>25</u></em><em><u> </u></em><em><u>square</u></em><em><u> </u></em><em><u>inches</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
