What is the solution to the system of equations 8x-10y=-23 and 9x+10y=-16

sammy [17]

8x-10y=-23
9x+10y=-16
(8x+9x)+(10y-10y)=(-23+(-16))
17x+0y=-39
x=-39/17
8(-39/17)-10y=-23
-312/17-10y=-23
-10y=-23+312/17
-10y=-79/17
y=79/170

Annette [7]

Answer:

$y =\fracc{4}{3}x+5$

m=4/3 and b=5

Step-by-step explanation:

We want to find the equation of the line passing through (3,9) and (6,13).

We determine the slope using:

$m = \frac{y_2-y_1}{x_2-x_1}$

Let:

$(x_1=3,y_1=9), (x_2=6,y_2=13)$

We substitute the points to get:

$m = \frac{13 - 9}{6 - 3} = \frac{4}{3}$

We now use the formula:

$y-y_1=m(x-x_1)$

We substitute to get:

$y - 9 = \frac{4}{3} (x - 3)$

Multiply through by 3 to get;

$3y - 27 = 4(x - 3)$

We expand further to get:

$3y - 27 = 4x - 12$

This implies that:

$4x - 3y = - 15$

We solve for y to get:

$y =\fracc{4}{3}x+5$

Therefore m=4/3 and b=5
