How do you write an equation in standard form given point (2,2) (0,-4)

notka56 [123]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 2) and (0, -4). Substitute:

$m=\dfrac{-4-2}{0-2}=\dfrac{-6}{-2}=3\\\\y-2=3(x-2)$

The standard form:

$Ax+By=C$

$y-2=3(x-2)$ use distributive property

$y-2=3x-6$ add 6 to both sides

$y+4=3x$ subtract y from both sides

$4=3x-y$

<h3>Answer: 3x - y = 4</h3>

Is the point (3, 4) a solution to the equation 3y = 2x +6 ? Explain why using evidence from your work

irinina [24]

Answer:

Yes

Step-by-step explanation:

When graphing it you can see that (3, 4) is clearly a solution. The proper equation using slope intercept form is y= 2/3x + 2.

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$
