Here is how to find the equation of the line using point-slope form
Formula for the equation of a line in <em>point-slope form</em>: y - y₁ = m(x - x₁)
Now that we have the formula, we plug in what we are given.
y - 9 = 4(x + 3)
We can covert this into slope-intercept form by solving for y.
Our equation for this line is: <em>y = 4x + 21</em>.
We can prove this by graphing the line, like so:
Answer:
1. $67.72
2. It's correct.
Step-by-step explanation:
1.
bill: $68.89
discount: $10
tip: 15%
Calculate the total with the discount.
68.89-10=58.89
Now calculate 15% of that.
Convert 15% to decimal by dividing by 100
Multiply
Add this to the original amount.

Calculate 20% of 148.25
Convert 20% to decimals by dividing by 100
Multiply
This is how much they will tip.
Add this to the original bill;
Answer:
(-3, 1) quadrant II (2)
Step-by-step explanation:
An image of the coordinate plane is show. The quadrants start at the top right and move around in the counter-clockwise direction. The x-axis is horizontal (side to side) and y-axis is vertical (up and down). Starting at the origin of the coordinate plane (0, 0) and going three blocks west (left) would put you at -3 on the x-axis. If you then proceed to go north (up) +1, you would now be at point (-3, 1) which is a (-x, +y) or in quadrant II.
