Question

Find the intercepts of the given line:
y=−6x+21

Answer 1

The y-intercept is 21 and the slope is -6/1
So (0,21) is the starting point and if you rise -6 and run 1 you get (15,1) and you keep doing that until u get a line

Answer 2

x-intercept = 3.5

y-intercept = 21

Explanation:

x-intercept is for y = 0

y-intercept is for x = 0

Substitute

For y = 0

-6x + 21 = 0 |subtract 21 from both sides

-6x = -21 |divdie both sides by (-6)

x = -21/(-6)

x = 21/6

x = 3.5

For x = 0

y = -6(0) + 21

y = 0 + 21

y = 21
