Answer:

y = 4x + -5

Step-by-step explanation:

Answer:

[tex]y=4x-5[/tex]

Step-by-step explanation:

parallel lines have the same gradient so line P's gradient would also be 4

line P's equation is [tex]y=4x+c[/tex] but we don't know the c variable yet, so we just plug in the coordinate values

[tex]-5=4(0)+c[/tex]

[tex]-5=c[/tex]

so line P's equation is [tex]y=4x-5[/tex]
