15. Write the slope-intercept form of the line described in the following:Parallel to 4x + 5y=20and passing through (12,4)
Amiraneli [1.4K]

Problem

Write the slope-intercept form of the line described in the following:

Parallel to 4x + 5y=20

and passing through (12,4)

Solution>

For this case we need to have the same slope, and if we write the equation given we see:

5y = 20 -4x

y = 4 -4/5 x

then the slope m = -4/5

and we also know a point given x= 12, y= 4 and we can do the following:

4 = -4/5 (12) +b

4 = -48/5 + b

And if we solve for the intercept we got:

b= 4 +48/5= -28/5

And our equation would be given by:

y = -4/5 x -28/5

Graph the line passing through the given point and having the given slope.<br> (1,-1), m= - 3/4
serious [3.7K]

Answer: y=-3x/4 -1/4

Step-by-step explanation:

y=mx+b

-1=-3/4 * 1 +b

-1=-3/4 + b

(-1=-3/4 + b)*4

-4=-3+4b

4b=-1

b=-1/4

y=-3x/4 -1/4

(a) Complete the table of values for y- 2x + 5<br> -<br> 0<br> 1<br> 2<br> 1<br> 5<br> Y
maxonik [38]

Answer:

Step-by-step explanation:

I think you meant y = -2x + 5.

x    y = -2x + 5

0                       5

1      -2(1) + 5 =   3

2     -2(2) + 5 =   1

Note that every time you increase x by 1, y decreases by 2.
