Answer:
gradient = =
y-intercept =
Explanation:
• The slope-intercept form of an equation takes the general form:
,
where:
m = slope,
c = y-intercept.
• We are given the equation:
To change this into the slope-intercept form, we must make y the subject:
[subtract
from both sides]
⇒
[divide both sides by 3]
⇒
• Comparing this equation with the general form equation, we see that:
m =
c =
.
This means that the gradient is
, and the y-intercept is
.
