QuestionFind the equation of the line with slope -2 which goes through the point (7, -1).Give your answer in slope-intercept form y = mx +b.Provide your answer below:

Sagot :

From the question, we can deduce the following:

• slope, m = -2

,

• The line goes through the points: (7, -1)

Let's find the equation of the line in slope-intercept form.

Apply the slope-intercept formula of a line:

y = mx + b

Where m is the slope and b is the y-intercept.

Here, the slope, m is = -2

We also have the point:

(x, y) ==> (7, -1)

Substitue -2 form, 7 for x, and -1 for y to find b.

y = mx + b

-1 = -2(7) + b

-1 = -14 + b

Add 14 to both sides:

-1 + 14 = -1 + 14 + b

13 = b

The y-intercept is 13.

Therefore, the equation of the line in slope-intercept form is:

y = -2x + 13

ANSWER:

y = -2x + 13
