Find the equation in slope-intercept form of the line parallel to y = 4x + 23 and passes through the point (2,3).

kupik [55]

Answer: y=4x-5

Step-by-step explanation:

The slope of y=4x+23 is:4 m=4

The parallel line needs to have the same slope of 4

Solve it using the "point-slope" equation of a line: y− y1 = 2(x − x1)

substitute or put in the point (2,3):

y − (3) = 4(x − 2)

y - 3 = 4x - 8

put it in slope intercept form y = mx + b

y = 4x − 5

Consider the line <img src="https://tex.z-dn.net/?f=%20y%3D%5Cfrac%7B2%7D%7B3%7D%20x%2B1%20" id="TexFormula1" title=" y=\frac{2}

miv72 [106K]

we are given equation of line

$y=\frac{2}{3} x+1$

Equation of perpendicular line:

Firstly , we will find slope of line

$y=\frac{2}{3} x+1$

we can compare it with

y=mx+b

we get

$m=\frac{2}{3}$

we know that

slope of perpendicular line will be -1/m

so, slope is

$\frac{-3}{2}$

It passes through point (-4,5)

so, we can use point slope form of line

$y-5=-\frac{3}{2}(x+4)$

we get

$y=-\frac{3}{2}x-1$ ..........Answer

Equation of parallel line:

Firstly , we will find slope of line

$y=\frac{2}{3} x+1$

we can compare it with

y=mx+b

we get

$m=\frac{2}{3}$

we know that

slope of parallel line always equal

so, slope is

$\frac{2}{3}$

It passes through point (-4,-5)

so, we can use point slope form of line

$y+5=\frac{2}{3}(x+4)$

we get

$y=\frac{2}{3}x-\frac{7}{3}$ ............Answer
