What is the equation of the following line written in general form?

Mathematics
1 answer:
stiks02 [169]3 years ago
4 0

Answer:

The correct answer is b) x - y + 1 = 0

Step-by-step explanation:

In order to find this, start by finding the slope using the two points given.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 2)/(4 - 1)

m = 3/3

m = 1

Now that we have the slope, we can plug into point slope form along with either point. Then we can solve for 0 to see which equation is correct.

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

-x + y - 2 = -1

-x + y - 1 = 0

x - y + 1 = 0

Answer

Attached the graph

Step by step explanation

Y = -1/4z + 5

Let's form the table values

Here z is the independent variable and y is the dependent values.

Let's take z = -1, 0, 1, 2 and find the corresponding y-values

<u>z                           y</u>

-1                         5.25

0                          5

1                           4.75

2                           4.5

Now let's plot the points and draw the graph.

Here is the graph.
