Hiw would i find the slope and y intercept of 2x + y =21

Slope = -2

Y-intercept = 21

Step-by-step explanation:

Given:

Equation of line:

To find slope and y-intercept.

Solution:

In order to find slope and y-intercept of the line, we will convert the equation into the slope intercept form which is given as:

where represents slope of line and represents y-intercept.

We have equation as :

We will solve for

Subtracting both sides by

⇒

⇒

Thus, the slope intercept form of the equation is given by:

Comparing it with the slope intercept equation, we see that slope and y-intercept .  (Answer)
