Question

13. Identify the y-intercept and the slope for each equation.

a. y=6x-3
b. y=-2 (x + 5)
c. y = 4 (-x + 1)
HELP ASAP

Answer 1

For a ) y = 6x - 3

`slope = m = 6\\y-intercept = c = -3\\`

For b ) y = -2x - 10

`slope = m = -2\\y-intercept = c = -10\\`

For c ) y = -4x + 4

`slope = m = -4\\y-intercept = c = 4\\`

Explanation:

Given:

a. y = 6x - 3

b. y = -2 (x + 5)

y = -2x - 10

c. y = 4 (-x + 1)

y = -4x + 4

To Find:

y-intercept and the slope for each equation = ?

Solution:

Slope-intercept Formula is given by

`y=mx+c`

Where,

m = slope

c = y-intercept

So on comparing the Given equations with the above Equation we get

For a ) y = 6x - 3

`slope = m = 6\\y-intercept = c = -3\\`

For b ) y = -2x - 10

`slope = m = -2\\y-intercept = c = -10\\`

For c ) y = -4x + 4

`slope = m = -4\\y-intercept = c = 4\\`
