Answer:

C. 3x + 4y = 10

Step-by-step explanation:

We shall change all the equation to the slope-intercept form, to get their slope and intercept.

To do the above, we will change it to the form y=mx + c

option A

4x + 3y = -10

subtract 4x from both-side of the equation

4x-4x + 3y = -4x - 10

3y = -4x - 10

Divide through the equation by 3

y = -4/3 x - 10/3

comparing the above equation with y=mx + c

The slope(m) is -4/3 and the  intercept(c)  is -10/3

OPTION B

4x + 3y = 10

Its almost the same with option A, except with the fact that the 10 is having a positive sign. This implies that its slope m = -4/3 and intercept(c) =10/3

OPTION C

3x + 4y = 10

Subtract 3x frrom both-side of the equation

3x - 3x + 4y =-3x + 10

4y = -3x + 10

Divide through the  equation by 4

4y/4 = -3x /4  + 10/4

y = -3/4x + 5/2

Comparing the above equation by y=mx + c

The slope (m) =-3/4   and the intercept(c) =5/2

Therefore the equation which describe a line having a slope of -3/4 and y-intercept 5/2  is  3x + 4y = 10

HELP PLEASE
iragen [17]

Answer:

third number = 4,

equation of y, y = 5x - 11

equation of n, n = 4x

equation of x, n + x + y =19

Step-by-step explanation:

so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19

10x = 30

x = 3.

Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11

15 - 11

4 = third number

Graph y -5 equals -2/3(x +9)​
Akimi4 [234]

Answer:

y = -2/3x - 1

Step-by-step explanation:

Let's solve for y.

y−5=−2/3(x+9)

Step 1: Add 5 to both sides.

y−5+5=−2/3x−6+5

y=−2/3x−1
