Answer:
Step-by-step explanation:
hello : let the equation y =ax+b
when x = 0 and y = -3 : -3=a(0)+b
so b= -3
when x = - 6 and y = -7: -7=a(-6)-3
6a=4 so : a=4/6=2/3
the equation is ; y =(2/3)x -3
verify ; 1) y-intercept -3 : for x=0 :
y =(2/3)(0)-3 = -3
2) passes through (-6,-7) : for x =-6
y = (2/3)(-6)-3 =-12/3 - 3 = -4-3=-7
