Answer:

The answer to your question is: y = 3/5 x - 2

Step-by-step explanation:

Data

5x + 3y = 15

A (5, 1)

Process

find the slope

5x + 3y = 15

3y = - 5x + 15

y = -(5/3) x + (15/3)

y = -(5/3) x + 5

Slope = m = -(5/3) but the lines are perpendicular then:

m = 3/5

New equation : (y - y1) = m(x - x1)

(y - 1) = 3/5 ( x - 5)

y - 1 = 3/5 x - 15/5

y = 3/5 x - 3 + 1

y = 3/5 x - 2

Answer:

Step-by-step explanation:

eq.of any line perpendicular to 5x+3y=15 is

3x-5y=c

because it passes through (5,1)

3*5-5*1=c

c=15-5=10

reqd. eq. is 3x-5y=10

5 y=3x-10

y=3/5 x-2

What is the slope of this graph?

larisa [96]

Since the slope is falling, instead of rising, it would be negative.

Now, on the line, I plotted (0, 2) and (-2, 10).

You would now plug this into the rise/run formula.
The formula is $\frac{y2 - y1}{x2 - x1}$

The equation would become,
$\frac{10 - 2}{-2 - 0}$ = $\frac{8}{-2}$ = -4

I believe the answer would be -4.

I hope this helps!

Okay, i'm pretty sure that if you make a residual plot its a plot using all those points labeled. So plot those points on a graph, if you are using a K12 diagram use the 1-10 as 100-1000 (basically add a zero to every number)
