Answer:
y-(-10)=3(x-(-4)
Explanation:
Using slope point formula (y-y1=m(x-x1)) we can use the given coordinates to fill in the equation.
y1=-10 & x1= -4
Put those into the equation: y-(-10)= m(x-(-4))
Now we need to find the slope using slope formula y2-y1/x2-x1: -19-(-10)/-7-(-4)= -9/-3
Simplify the slope: -9/-3= 3
End up with your final equation: y-(-10)=3(x-(-4))
