Which ordered pair is a solution of the equation? −7x+3y=2

lana66690 [7]

Answer:

(-2/7, 2/3)

step-by-step explanation:
-7x + 3y = 2
x = 0
-7(0) + 3y = 2
3y = 2
/3 /3
y = 2/3
y = 0
-7x + 3(0) = 2
-7x = 2
/-7 /-7
x = -2/7
(-2/7, 2/3)

What is 15=-3y+21x in slope intercept form?

sweet [91]

Slope intercept form = Y = Mx + B

15 = -3y + 21x

3y = 21x - 15

Y = 21/3 X - 15/3

Y = 7x - 5 = SI Form

Look at the system of equations below.

Paul [167]

Answer:

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=2,\:y=-1$

Step-by-step explanation:

Considering the system of the equation

$\begin{bmatrix}y=-2x+3\\ 4x-3y=11\end{bmatrix}$

$\mathrm{Subsititute\:}y=-2x+3$

$\begin{bmatrix}4x-3\left(-2x+3\right)=11\end{bmatrix}$

$\mathrm{Isolate}\:x\:\mathrm{for}\:4x-3\left(-2x+3\right)=11$

$4x-3\left(-2x+3\right)=11$

$4x+6x-9=11$

$10x-9=11$

$10x-9+9=11+9$

$10x=20$

$x=2$

$\mathrm{For\:}y=-2x+3$

$\mathrm{Subsititute\:}x=2$

$y=-2\cdot \:2+3$

$y=-1$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=2,\:y=-1$
