Question

Write the equation of the line in slope-intercept form and identify the slope.
−5x + 10y = 20

Answer 1

Slope = 1/2

Explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question the equation is

- 5x + 10y = 20

To find the slope we must first write the equation in the form above

- 5x + 10y = 20

Move - 5x to the right side of the equation

10y = 5x + 20

Divide both sides by 10

We have

`y = (5)/(10) x + (20)/(10)`

`y = (1)/(2) x + 10`

Comparing with the general form of equation above

Slope / m = 1/2

Hope this helps you
