Please help me, I'm doing a test.

Answer:

(3,4)

Step-by-step explanation:

first you're going to solve the equation -2x

your equation should now be: $\left \{ {{-2x+3y\\=6} \atop {-2x=2-2y}} \right.$

next you're going to substitute the given value of -2x into the equation $-2x+3y=6$

so your equation should now be: $2-2y+3y=6$

next you're going to solve the equation for y

equation should now be: y=4

than you're going to substitute the given value of y into the equation $-2x=2-2$ × $4$

then you're going to solve the equation for x

your equation should now be: x=3

then the possible solution of the system is the order pair: (x,y)=(3,4)

For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.

Veseljchak [2.6K]

The y intercept is where the line crosses the y axis, this is also when x=0
the x intercept is where the line crosses the x axis, this is also when y=0

to find them, set to zero each and find the other value

y intercept, set x=0
y=-2(0)-3
y=0-3
y=-3
y intercept is y=-3 or (0,-3)

x intercept is when y=0
0=-2x-3
add 3
3=-2x
divdie by -2
-1.5=x
x intercpet is (-3/2,0) or x=-3/2
