Answer:
<h2>y = 6x + 9</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept → (0, b).
Parallel lines have the same slope.
Therefore if <em>k</em>: y = 6x + 7 → m = 6, and <em>l</em>: y = mx +b,
then <em>l</em> is parallel to <em>k</em> if m = 6.
We have the equation: y = 6x + b.
The line <em>l</em> passes through (0, 9). Therefore b = 9.
Finally we have:
<em>y = 6x + 9</em>
