OK, 60 pounds is weight.... cost is money.... what the what?
<span>y = <span>x2 </span>+ 5x + 36
y = (<span>x2 </span>− 5x − 36)</span>
<span>y = (<span>x2 </span>− 9x + 4x − 36)</span>
<span>y = [x (x − 9) + 4 (x − 9)]</span>
<span>y = (x − 9)(x + 4)</span>
Answer:
y = 1/2x + 4
Step-by-step explanation:
Use the formula for the equation of a line.
y = mx + b
Where m is the slope, and b is the y-intercept.
The slope is given.
y = 1/2x + b
The points (x, y) are given.
(4, 6)
Put y as 6 and x as 4, solve for b.
6 = 1/2(4) + b
6 = 2 + b
6 - 2 = b
4 = b
The y-intercept is 4 or (0, 4).
The equation of the line is y = 1/2x + 4.
