Answer:

The solution of the system of equations is the point (-3,0)

Step-by-step explanation:

we have

$-3x+y=9$ -----> equation A

$2x-y=-6$ -----> equation B

Adds equation A and equation B

$-3x+y=9\\2x-y=-6\\------\\-3x+2x=9-6\\-x=3\\x=-3$

Find the value of y

$-3(-3)+y=9$

$9+y=9$

$y=9-9=0$

The solution of the system of equations is the point (-3,0)

What is the equation of a line that passes through the points (3, 6) and (8, 4) in slope intercept form?

MrMuchimi

Answer:

$y=-\frac{2}{5}x +8.4$

Step-by-step explanation:

Gradient

$m =\frac{y-y1}{x-x1}$

$m = \frac{6-4}{3-8}$

$m=-\frac{2}{5}$

Equation of a line

$(y-y1)=m(x-x1)\\$

- Sub one set of points into equation

$(y-6)= -\frac{2}{5} (x-6)$

$y=-\frac{2}{5}x +8.4$
