Math, asked by noahtrufin, 1 year ago

What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of −56 ? a.y+4=−56(x+8) b. y−4=−56(x+8) c. y+4=−56(x−8) d.y−4=−56(x−8)

need help asap

Goes through 8,-4=>x=8
Y=-4
Slope=-56

m=-56

(y-y1)=m(x-x1)
y-(-4)=-56(x-8)
y+4=-56(x-8)

Option c.. Hope it will help you

noahtrufin: plz

divya1261: Wait a sec

divya1261: Done

divya1261: It didnt asked to expamd earlier i expanded it not its fixed

noahtrufin: u didint fix it but what evri still dont know the answer!!!!

divya1261: Do u have answer means which is correct!

divya1261: Uf

divya1261: I m class 9 student n this is of class 10 i think

divya1261: I hv studied

noahtrufin: ok but this still not the answer i wanted!

Solution:

Equation of line passing through (a,b) and having slope m is given by

→ $\frac{y-b}{x-a} = m$

So, equation of line passing through (8,-4) and has a slope of -56 is given by

→ $\frac{y + 4}{x-8} = -56$

→ (y+4) = -56 (x -8)

Option C which is → (y+4) = -56 (x -8) is correct.
