Write the equation of the line in fully simplified slope-intercept form.
Nataliya [291]

Answer:

y=-\frac{1}{4} x-6

Step-by-step explanation:

The slope-intercept form is y=mx+c, where m is the slope of the line and c is where the line crosses the y-axis.

To calculate m we can use the formula m = \frac{dy}{dx} where dy is the difference in y between two points and dx is the difference between x.

Information we can get from the graph given: c=-6. Since c is the point at which the line crosses the y-axis.

To find m let's get two points from the graph.

Point 1: (4,-7)

Point 2: (8,-8)

Now use the equation m = \frac{dy}{dx}.

m = \frac{-7 - (-8)}{4-8}  = -\frac{1}{4}.

Now we have m and c, let's put them back into the general equation.

y=-\frac{1}{4} x-6

The given expression 8(4)^2+2^4 is equal to 144 or 12^2

<em><u>Solution:</u></em>

Given expression is:

8(4)^2+2^4

We have to evaluate the above given expression

We know that,

(4)^2 = 4 \times 4 = 16

2^4 = 2 \times 2 \times 2 \times 2=16

Substituting these in above given expression, we get

8(4)^2+2^4=8 \times 16+16\\\\8(4)^2+2^4= 128+16\\\\8(4)^2+2^4=144

Also we know that,

12 \times 12 = 144

Therefore,

8(4)^2+2^4=144 = 12 \times 12 = 12^2

Thus the given expression 8(4)^2+2^4 is equal to 144 or 12^2
