Question

Slope 1/3; y intercept = -1

slope -2/5; y intercept = 0
slope= -1; y intercept= 4

give me the slope intercept form equation for this

Answer 1

`\qquad \qquad\huge \underline{\boxed{\sf Answer}}`

Here's the solution ~

Slope intercept form of an equation is :

`\qquad \sf  \dashrightarrow \: y = mx + c`

where,

• m = slope

• c = y - intercept

Now, let's find the required equations ~

A.) Slope = 1/3 and y intercept = -1

`\qquad \sf  \dashrightarrow \: y = (1)/(3) x - 1`

B.) Slope = -2/5 and y intercept = 0

`\qquad \sf  \dashrightarrow \: y = - (2)/(5) x`

C.) Slope = - 1 and y intercept = 4

`\qquad \sf  \dashrightarrow \: y = - x + 4`

Answer 2

Given below.

Explanation:

using the formula :

y = mx + c ....where m is the slope and c is the y intercept

(a) if slope 1/3; y intercept = -1

y = x/3 - 1

(b) if slope -2/5; y intercept = 0

y = -2x/5 + 0

y = -2x/5

(c) if slope= -1; y intercept= 4

y = -1x + 4

y = -x + 4
