Y=-x+5<br> Y=x+1<br> Solve the system
Elis [28]

Answer:

y =  - x + 5 \\ y = x + 1 \\   - x + 5 = x + 1 \\  - 2x =  - 4  \\ x = 2 \\ y = 2 + 1 = 3 \\ y = 3

Therefore the answer is:

x=2; y=3

Good luck!

Which of the following point-slope form equations could be produced with the points (4, 5) and (-3, -5)?
NikAS [45]

Answer:

<em>Equation; y = 1 3 / 7x - 5 / 7</em>

Step-by-step explanation:

First consider the slope of this equation we must derive;

Slope Formula = Rise / Run,

y2 - y1 / x2 - x1 ⇒

5 - ( - 5 ) / 4 - ( - 3 ) ⇒

10 / 7 ⇒ Slope : 1 3 / 7

So far we can formulate an equation as such;

y = 1 3 / 7 * x + b, <em>where b ⇒ y - intercept</em>

Given one of the points, substitute into this equation solving for b;

5 = 1 3 / 7 * ( 4 ) + b,

5 = 40 / 7 + b,

b = - 5 / 7

From this we can derive one point - slope from equation to be :

<em>Equation; y = 1 3 / 7x - 5 / 7</em>
