describe the error Kevin made. circle the places in the drawing of Kevin's solution where he made an error
Tresset [83]
The error that Kevin made was he did not include two units (see the circled areas) while counting the units. He counted the units there as one instead of two at those junctions. The correct measure of the perimeter of the figure is 20 units.

Use the information given to enter an equation in standard form.
Greeley [361]

Answer:

y = -2x + 25

Step-by-step explanation:

A standard equation can be in slope-intercept form: y = mx + b

m is the slope, b is the y-intercept.

Plug in the given slope.

y = -2x + b

To find b, plug in the given point (9, 7).

7 = -2(9) + b

Multiply.

7 = -18 + b

Add 18 to both sides to find b.

25 = b

Plug this into your standard equation.

y = -2x + 25

Check by plugging in the given point again.

7 = -2(9) + 25

7 = -18 + 25

7 = 7

Your answer is correct!

Hope this helps!
