Question

Q1: Find a general linear equation of the straight line that has the indicated properties
a) Passes through (-5,5) and has slope - 12
b) Has slope - 12 and y-intercept -3

Answer 1

a) Y- Y0= k × (X-X0); 

X0 =-5; 

Y0 =5; 

K=-12; 

Y- 5= (-12) × (X-(-5)); 

Y= -12X-55; 

b) Y- Y0= k × (X-X0); 

X0 =0; 

Y0 =-3; 

K=-12; 

Y- (-3)= (-12) × (X-0); 

Y= -12X-3;
