Answer:

The required equation in factored form is: \mathbf{y=-4(x+2)(x-1)}

Step-by-step explanation:

In this question we need to find the equation of the graph in factored form.

The factored form will be: f(x)=a(x-r_1)(x-r_2)..

where a is y-intercept and r₁, r₂ are x-intercepts

X-intercepts

When y=0, the values of x axis are known as x-intercepts

Y-intercepts

When x=0, the values of y-axis are known as y-intercepts.

Looking at the graph finding x-intercepts

When y=0 x=-2 and 1

So, we have

r₁ = -2

r₂ = 1

Looking at the graph finding y-intercepts

When x=0, y=-4

So, a = -4

Putting values in the formula we will get:

f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)

So, the required equation in factored form is: \mathbf{y=-4(x+2)(x-1)}

Solve using elimination.<br><br><br> 9x + 4y = -6<br><br><br> -7x + y = -20
zaharov [31]
9x+4y=-6
4(-7x+y=-20)

9x+4y=-6
-(-28x+4y=-80)

37x=74

x=74/37

x=2
