A linear equation will contain  a term in x  has the highest degree.  For example  y = 2x - 5 . A non linear will contain terms with exponents 2 or higher 
eg x^2 - 2x - 5  is nonlinear.

Use point-slope form to write the equation of a line that passes through the point
Ymorist [56]

Answer:

y= -2x-22.

Step-by-step explanation:

1) the slope-interception common form is y=s*x+i, where 's' and 'i' are the slope and interception, unknown numbers;

2) if x₁= -3; y₁= -16, and s=-2, then the equation of the required line can be written in the point-interception form y-y₁=s(x-x₁); ⇔ y+16= -2(x+3);

3) the required equation in slope-interception form is:

y+16= -2x-6; ⇒ y= -2x-22.

note, the provided solution is not the only and shortest way.

The line AB has the midpoint of (2,5) A has coordinates (1,7) find the coordinates of B
Pavel [41]

Answer:

Point B is at (3,3)

Step-by-step explanation:

the mid point is (2,5) and A is at (1,7)

first find the slope:

y1 - y2/x1 - x2

7 - 5/1 - 2

2/-1

-2/1

then go down 2 units and right 1 unit from (2,5):

(2 + 1, 5 - 2) => (3,3)

On A piece of paper graph the system of equations. Then determine which answer choice matches the graph you drew and identify a
hodyreva [135]

Answer:

Final graph is attached.

Solution is x=2, y=3

Step-by-step explanation:

As we have to solve by graphing to let's graph y=2x-1 first.

we are free to plug any number for x say x=0 and x=2

when x=0 then y=2x-1 changes to

y=2(0)-1=0-1=-1

Hence point is (0,-1)

Similarly

when x=2 then y=2x-1 changes to

y=2(2)-1=4-1=3

Hence point is (2,3).

Now we graph both points (0,-1) and (2,3) then join them by a straight line.


We repeat exactly same process for other line y=-x+5 and get points (0,5) and (2,3)

Now graph both to see the intersection point of both lines

We see that both lines intersect at point (2,3)

<u>Hence final answer is (2,3) or we can also write x=2, y=3.</u>
