Need done and Hurry
kicyunya [14]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (5, - 2) and (x₂, y₂ ) = (3, 6)

m = \frac{6+2}{3-5}= \frac{8}{-2} = - 4

Using (a, b) = (5, - 2), then

y + 2 = - 4(x - 5) ← third on list

-----------------------------------------------

Using (a, b) = (3, 6), then

y - 6 = -4(x - 3)

Graph the system of inequalities y&gt; 2x-3 and 3y-x≤6
Veronika [31]
Y > 2x - 3
3y - x ≤ 6
       ↓
y = 2x - 3
3y - x = 6

    3(2x - 3) - x = 6
3(2x) - 3(3) - x = 6
        6x - 9 - x = 6
        6x - x - 9 = 6
             5x - 9 = 6
             <u>    + 9 + 9</u>
                  <u>5x</u> = <u>15</u>
                   5      5
                    x = 3
y = 2x - 3
y = 2(3) - 3
y = 6 - 3
y = 3
(x, y) = (3, 3)
