Answer: y = 4x + 5
Step-by-step explanation:
The general equation of a line is y = mx + d ,
m = slope
d indicates the y-intercept, when x=0 , Y=5 => (0,5)
In the given line m = 3 , so that is the slope.
This slope has an angle = arctan(3) = 71.56º
If we need a steeper line, we have to increase m,
By example y = 4x + 5 , would have the same y-intercept but would be steeper.
This new line has a greater slope, with an angle = arctan (4) = 75.96º
X - the number of pencils
y - the number of pens
She has twice as many pencils as she has pens.
Tom borrows a pen, so she has y-1 pens. Now she has ten less pens than pencils.
Set 2y and y+9 equal to each other:
She has 9 pens.
