Write the equation of the line that is parallel to the graph of y=-4x-9 and whose y intercept is 3

1 answer:

8 0

Y = -4x - 9
The new line has the same slope as the one above, that is - 4
A y intercept means the point (in this case) is 0,3 [The x value is 3]

y = -4x + b Now use (0,3)
3 = 0 + b
b = 3

y = - 4x + 3 is the line you want.

$(\stackrel{x_1}{1}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4}-\stackrel{y1}{(-2)}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{4+2}{2}\implies \cfrac{6}{2}\implies 3$
