Write the slope-intercept form of the equation of the line (y=Mx+b) through the given point:
OleMash [197]

Answer:

<h2>          y = 2x + 6</h2>

Step-by-step explanation:

M=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-0}{-2-(-3)}=\dfrac21=2

y = 2x + b  passes through point (-3, 0), so:

0 = 2(-3) + b

0 = -6 + b

b = 6

Therefore the equation:  <u>y = 2x + 6</u>

5 Consider this system of equations:<br> 5x + y = -2<br> 2x - 2y=4
Ilia_Sergeevich [38]

Answer:

x  = 0

  y  = -2

Step-by-step explanation:

The given system of equation are:

   5x + y = -2

   2x - 2y = 4  

The problem here is to find x and y from the expression

   5x + y = -2     ----- i

   2x - 2y = 4    ---- ii

 So;

i x 2 :  10x + 2y  = -4     ----  iii

ii x 5 :  10x - 10y  = 20    ----- iv

   iii - iv;   12y  = -24

                  y  = -2

    Now find x;

             5x + y  = -2

             5x  - 2  = -2

                  x  = 0
