Answer:
Given below.
Step-by-step 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

Here's the solution ~
Slope intercept form of an equation is :
[tex]\qquad \sf \dashrightarrow \: y = mx + c[/tex]
where,
- m = slope
- c = y - intercept
Now, let's find the required equations ~
A.) Slope = 1/3 and y intercept = -1
[tex]\qquad \sf \dashrightarrow \: y = \dfrac{1}{3} x - 1[/tex]
B.) Slope = -2/5 and y intercept = 0
[tex]\qquad \sf \dashrightarrow \: y = - \dfrac{2}{5} x[/tex]
C.) Slope = - 1 and y intercept = 4
[tex]\qquad \sf \dashrightarrow \: y = - x + 4[/tex]
