Question

2. Which equation describes a line that has

a slope of (4/5) and a y-intercept of (2/5)?
A) 5y + 4x = 2
C) Sy - 4x = 2
B) 4x5y = 2
D) -5y - 4x = 2

Answer 1

c,5y-4x=2

Explanation:

y=mx+b

y=4/5x+2/5

so m=4/5, and y intercept x=0 so y=2/5

Answer 2

C

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m =
`(4)/(5)` and c =
`(2)/(5)` , then

y =
`(4)/(5)` x +
`(2)/(5)` ( multiply through by 5 to clear the fractions )

5y = 4x + 2 ( subtract 4x from both sides )

5y - 4x = 2 → C
