Answer: the company has to increase its revenue in 33.33%

48 million ----- 100%

16 million -------X

X= 1600/48    X= 33.33%

How do you find a y-intercept
ser-zykov [4K]

Answer:

Explanation:

ok so there so many ways i can tell explian

1. The slope-intercept form of a line is: y=mx+b where m is the slope and b is the y-intercept. The y-intercept is always where the line intersects the y-axis, and will always appear as (0,b) in coordinate form.

2. how to find the Y-intercept when given two points

Steps

a.  Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)

b, Substitute the slope(m) in the slope-intercept form of the equation.

c, Substitute either point into the equation. You can use either (3,5) or(6,11).

d,Solve for b, which is the y-intercept of the line.

e, Substitute b, into the equation.

3. how to find the Y intercept in a quadratic equation

To find the y-intercept let x = 0 and solve for y. Step 3: Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form)
