Answer:

Step-by-step explanation:

(2x-5)(x+6)=0

either 2x-5=0               Or, x+6=0

2x-5=0

2x=0+5

x=5/2

x+6=0

x=0-6

x=-6

so x=5/2 , x=-6

Y + 4/9 = 2/3 Solve the equation..
emmainna [20.7K]
Y + 4/9 = 2/3

Let's convert 2/3 into 6/9 so it will be easier to subtract.

Y + 4/9 = 6/9
Subtract 4/9 on both sides.

Y = 2/9 Hope this helps!

<h2>Answers:</h2>

Question 1: The equations share the same slope, but different y-intercepts.

Question 2: Option B (y = 2x + 1)

<h2>Explanations:</h2><h3>For Question 1:</h3>

Both equations are written in slope intercept form.

y = mx+b\\\\\text{m - slope}\\\text{b - y-intercept}

The equations we have are:

\left \{ {{y=2x} \atop {y=2x-7}} \right.

Both equations share the same slope of 2. However, they have different y-intercepts.

y = 2x can be written as y = 2x + 0.

Usually if you only have the slope in your equation then the y-intercept is the origin, or (0, 0).

The second equation's y-intercept is -7. It takes 'b's place.

<h3>For Question 2: </h3>

We are given a graph and we need to find a equation.

According to the graph, the line passes at (0, 1). 1 is the y - intercept.

Since y = 2x + 1 is the only option with 1 as the y - intercept, it should be the correct answer.

I'll do the slope as well to verify our answer.

I will use the points (-1, -1) and (1, 3).

m=\frac{3-(-1)}{1-(-1)}=\frac{4}{2} =\boxed{2}

The correct answer should be y = 2x+1.

Hope this helps you.
