A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx
tester [92]

Answer:

b=-18

Step-by-step explanation:

If a line that passes through the point P(x_o,y_o)and it has slope m, the equation of the line is:

y-y_o=m(x-x_o)~=>y=mx+y_o-mx_o~=>b=y_o-mx_o\\\\b=-6-4(3)=-18

x - y = 11
2x + y = 19
2x - 2y = 22
2x + y = 19
-3y = 3
y = -1
x + 1 = 11
x = 10
(10, -1)

6.
-6x + 6y = 6
-6x + 3y = -12
3y = 18
y = 6
-6x + 36 = 6
-6x = -30
x = 5

Julio just bought a $267,900 house. he had a 20 year mortgage with a fixed rate of 5.875%. julio’s monthly payments are $1,558.0
boyakko [2]

The percent of the purchase price for Julio’s down payment was C. 18%

<h3>What is Interest Rate?</h3>

This refers to the amount of money that is added to a loan collected by a person, for when he makes repayment.

Hence,

Given that

  • PMT monthly payment 1558.09
  • R interest rate 0.05875
  • K compounded monthly 12 because the payment is monthly
  • N time 20 years
  • Pv present value?

We use the formula Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]

Pv= 1,558.09×((1−(1+0.05875÷12)^(−12×20))÷(0.05875÷12))

=219,684.92

Next thing to do is make a subtraction to get the down payment:

267,900−219,684.92=48,215.08

Then the percentage would be:

48,215.08÷267,900= 18% approx.
