Answer:
y= -3.5x-7
Step-by-step explanation:
insert (-2,0), (0,-7) into the equation y=ax+b
=> 0= -2a+b, -7=b
solve a, b
=> -2a-7=0
=> -2a=7
=> a= -3.5, b= -7
insert a, b into the equation y=ax+b
1.
(-2,0) (0,-7) y2-y1
-----------------
x2-x1
-7-0= -7
0- (-2)= 2 ------>>> -7/2 =m or slope
2.
y= -7/2x+b to find b u plug in one pair of coordinates for example (-2,0)
and use inverse properties to find b
0 = -7/2(-2) + b
14/2 = 7
0= 7+b
-7 -7
-----------
-7=b
3.
y=-7/2x-7
