Question

Identify the slope and y-intercept of each of the following. Please help ^^^^ a. y = x + 100 b. y = 2x - 5 c. y = 0.5x

Answer 1

a. y=x+100
y-inercept=100
b. y=2x-5
slope=2 y-intercept=5
c. y=0.5x
slope=0.5

Answer 2

see explanation

Explanation:

The equation of a line in slope- intercept form is

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

All 3 equations are in this form

(a)

y = x + 100

with slope m = 1 and y- intercept c = 100

(b)

y = 2x - 5

with slope m = 2 and y- intercept = - 5

(c)

y = 0.5x ( or y = 0.5x + 0 )

with slope m = 0.5 and y- intercept c = 0
