a(x-r1)(x-r2)
r meaning root or x intercept
example:
-2(x-2)(x+0.05)
Hope this helped(;
100% + 25% is 120% then 120 as a decimal 1.20 then you do 1.20 x 65 = 78
soo the selling price is $78
Answer:
So the y-intercept is 2 while the slope is -7/2.
Step-by-step explanation:
We are going to write this in slope-intercept form because it tells us the slope,m, and the y-intercept,b.
Slope-intercept form is y=mx+b.
So our goal is to solve for y.
-7x-2y=-4
Add 7x on both sides:
-2y=7x-4
Divide both sides by -2:

Separate the fraction:

Simplify:

If we compare this to y=mx+b, we see m is -7/2 and b is 2.
So the y-intercept is 2 while the slope is -7/2.
