Slope intercept form

Question

write 5X + 10Y - 20 = 0 in the slope intercept form

Answer 1

Leah,

 

Slope intercept form is  y = mx + c

 

The given eq. is 5x + 10y -20 = 0

 

Add 20 to both sides 5 x + 10y = 20

Subtract 5x from both sides 10y = -5x + 20

Divide both sides by 10

y = -0.5 x + 2

 

So the slope is -0.5 and y intercept is 20
