No she didn't write the decimal correctly. This is because 50 as a decimal is 0.50 and not 0.05
F (x)=y
y=2x-9
X Y
-2 -15 y=2 (-2)-9
y=-4+-9
y=-15
-1 -11 y=2 (-1)-9
y=-2+-9
y=-11
0 -9 y=2 (0)-9
y=0+-9
y=-9
1 -7 y=2 (1)-9
y=2+-9
y=-1
2 -5 y=2 (2)-9
y=4+-9
y=-5
Here is all the work
Answer:
y=1/2x+3
Step-by-step explanation:
y-y1=m(x-x1)
y-1=1/2(x+4)
y=1/2x+3
