<u>Answer:</u>

gradient = = 
y-intercept = 
<u>Step-by-step explanation:</u>
• 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
.
<span>(2x + 2) - (3x + 11)
Subtract 3x from 2x while subtracting 11 from 2
Final Answer: B.) -x - 9</span>
x=2, y=3 is a pair of a equations right there, so a correct solution.
