Give the slope and the y-intercept of the line y = x – 4.
Airida [17]

Given:

The equation of a line is

y=x-4

To find:

The slope and y-intercept of the line.

Solution:

We have,

y=x-4          ...(i)

The slope intercept form of a line is

y=mx+b            ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

m=1,b=-4

Slope of the line = 1

y-intercept of the line = -4

The coordinate form of y-intercept is (0,b). So, the y-intercept of the given line is (0,-4).

Therefore, the slope of the line is 1 and the y-intercept is (0,-4).

a person invested $6300 for 1 year part at 8% part at 10% and the remainder at 15%. The total annual income from these investmen
Lunna [17]

Answer:

Step-by-step explanation:

let x be part at 8%, y be part at 10% and z be part at 15%

(1) x+y+z=6300

the amount of money invested at 15% was $100 more than the amounts invested at 8% and 10% combined. so

(2) z=x+y+100

The total annual income from these investments was $766. so

0.08x+0.1y+0.15z=766 or

(3) 8x+10y+15z=76600

substitute (2) into (1)

x+y+x+y+100=6300

(4) 2x+2y=6200

substitute (2) inot (3)

8x+10y+15(x+y+100)=76600

(5) 23x+25y=75100

solving (4) n (5)

x=1200

y=1900

z=1200+1900+100=3200
