Equation that can be used to find the equation of line m is

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

Given :

Lines l and M are parallel. Line l can be represented by the equation 3x+4y=8

Line m passes through the point (2, -5)

Equation of line L is 3x+4y=8

Lets find out the slope of the given equation by writing it in y=mx+b form

where m is the slope

$3x+4y=8\\4y=-3x+8\\y=\frac{-3}{4}x +2$

the slope of line L is $\frac{-3}{4}$

Slope of parallel lines are equal

slope of parallel line M is also $\frac{-3}{4}$

Line M passes through (2,-5)

We use point slope formula to find equation of line m

$y-y_1=m(x-x_1)\\y+5=\frac{-3}{4} (x-2)\\$

Multiply both sides by 4

$4(y+5)=-3 (x-2)\\4y+20=-3x+6\\3x+4y+20=6\\3x+4y=14$

equation can be used to find the equation of line is

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

3y - 4x + 7 = 0

Step-by-step explanation

The equation of the line l in point slope form is expressed as;

y-y0 = m(x-x0)

Get the slope m of the known line

Given the line 3x+4y=8

4y = -3x+8

y = -3x/4 + 2

m = -3/4

The slope of the line m = -1/(-3/4) = 4/3

Substitute m = 4/3 and the point (2,-5) into the expression above;

y - (-5) = 4/3(x-2)

y+5 = 4/3 x + 8/3

Multiply through by 3;

3y + 15 = 4x + 8

3y-4x + 15 - 8 = 0

3y - 4x + 7 = 0

Hence the equation that can be used to find the equation of line m is 3y - 4x + 7 = 0

Answer from: Quest

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i. when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them. .

Answer from: Quest

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
