How do I write the equation of the line which passes through (5, –2) and is parallel to x = 4 ? It doesn't tell me to do so in slope intercept form.

Question

hba · Answer

the formula is y-y1=m(x-x1)

hba · Answer

y-5=4(x-5)
y-5=4x-20
4x-y-15=0 is the answer

thank you so much! and how would i do the same for a line perpendicular, if you don't mind answering that as well?

hba · Answer

the formula is y-y1=-1/m(x-x1)

hba · Answer

one more thing i by mistaken wrote y1 as 5 in the solution i showed it should be -2 really sorry about that
