Answer:
1)y=
x -5
2)y= -
x +

Explanation:
1) in order to write an equation in y=mx+b:
we just need to figure out what our 'b' is given the info:
y=mx+b
-5 = 1/4 (0) +b
-5 = 0+b
b=-5
Hence, the equation in slope-intercept form:
y=
x -5
2) y=mx+b
4=(-2/3)(1) +b
4= -2/3 +b
4+ 2/3 =b
14/3 = b
Hence, the equation: y= -
x +
