Answer:
(1) The slope intercept should be y=1/2x-5
So the table should be
x y point
-2 -6 (-2,-6)
0 -5 (0,-5)
2 -4 (2,-4)
(2) The slope -5/4
Step-by-step explanation:
(1) The reason why when she graphed the points is incorrect is because she needs to graph it in point slope form not in standard form and when she used the equation.
To find the slope intercept form you need to get the y on one side by itself:
x-2y=10
Subtract x on both sides:
-2y=-x+10
Divide by -2 on both sides:
y=1/2x-5
(2)The formula for the slope is y2-y1/x2-x1
-2-3/5-1
Which is -5/4
Thus the slope is -5/4
Hope this helps!
