Use the graph to find the solution y=x+4 y=-2x-2

(-2 , 2)

Step-by-step explanation:

y=x+4

y=-2x-2

x+4=-2x-2

3x=-6

x=-2

y=2

graph attached

Given to equations to us are ,

And we need to find the solution using graphical method.

So , after plotting the graph of both equations the point where both lines intersect will be the solution of the graph.

And , for plotting we need at least two points .

For equation (1) :-

When x = (-4) .

When x = (-3)

For equation 2 :-

When x = (-1) .

When x = (0)

Now , let's plot their graphs. Graph is in attachment. Hence on plotting the graph we see that both the lines Intersect on (-2,2) . Hence x = -2 and y = 2 is the solution of the given linear equation.

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
