ASAP please help me I don’t not know how to find the Y intercept from two points

1 answer:

5 0

They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

Then, you can plug in one of the two points $(x_1,y_1)$ or $(x_2,y_2)$ into the formula y=mx+b to solve for b, which is your y-intercept.

Katie invested a total of $4000, part at 2% simple interest and part at 3% simple interest. At the end of 1 year, the inves

Fiesta28 [93]

Answer:

$3000

$1000

Step-by-step explanation:

the formula for simple interest = principal x time x interest rate

let the amount invested in the 2% investment be a

let the amount invested in the 3% investment be (4000 - a)

(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90

0.02a + 120 - 0.03a = 90

Collect like terms and solve for a

0.01a = 30

a = $3000

The amount invested in the 3% investment be (4000 - a) = $4000 - $3000 = $1000
