Find the intercepts of the given line:
y=−6x+21
2 answers:
The y-intercept is 21 and the slope is -6/1
Answer:
<h2>x-intercept = 3.5</h2><h2>y-intercept = 21</h2>
Step-by-step explanation:
x-intercept is for y = 0
y-intercept is for x = 0
Substitute
For y = 0
-6x + 21 = 0 |<em>subtract 21 from both sides</em>
-6x = -21 |<em>divdie both sides by (-6)</em>
x = -21/(-6)
x = 21/6
x = 3.5
For x = 0
y = -6(0) + 21
y = 0 + 21
y = 21
