y-1=-\frac{5}{4}\left(x-3\right)
Fraction \frac{-5}{4} can be rewritten as -\frac{5}{4} by extracting the negative sign.
y-1=-\frac{5}{4}x+\frac{15}{4}
Use the distributive property to multiply -\frac{5}{4} by x-3.
-\frac{5}{4}x+\frac{15}{4}=y-1
Swap sides so that all variable terms are on the left hand side.
-\frac{5}{4}x=y-1-\frac{15}{4}
Subtract \frac{15}{4} from both sides.
-\frac{5}{4}x=y-\frac{19}{4}
Subtract \frac{15}{4} from -1 to get -\frac{19}{4}.
\frac{-\frac{5}{4}x}{-\frac{5}{4}}=\frac{y-\frac{19}{4}}{-\frac{5}{4}}
Divide both sides of the equation by -\frac{5}{4}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-\frac{19}{4}}{-\frac{5}{4}}
Dividing by -\frac{5}{4} undoes the multiplication by -\frac{5}{4}.
x=\frac{19-4y}{5}
Divide y-\frac{19}{4} by -\frac{5}{4} by multiplying y-\frac{19}{4} by the reciprocal of -\frac{5}{4}.
y-1=-\frac{5}{4}\left(x-3\right)
Fraction \frac{-5}{4} can be rewritten as -\frac{5}{4} by extracting the negative sign.
y-1=-\frac{5}{4}x+\frac{15}{4}
Use the distributive property to multiply -\frac{5}{4} by x-3.
y=-\frac{5}{4}x+\frac{15}{4}+1
Add 1 to both sides.
y=-\frac{5}{4}x+\frac{19}{4}
Add \frac{15}{4} and 1 to get \frac{19}{4}.
