Answer:
The value of a is 9 and b is -8
Step-by-step explanation:
We need to find two numbers that add up or subtract off to 1.
Then we also use the same two numbers that multiply and get -72.
Let's see:-
- 9 and -8 seem like correct values.
Because 9+(-8) is 9-8 = 1
And 9(-8) is -72.
Therefore:
The value of a is 9 and the value of b is -8 according to form of (x+a)(x+b)
Given two points, the equation of the line in slope form can be obtained using this equation
Now we can name the points
x1 = 2, y1 = 8
x2 = 4 , y2 =9
These coordinates can then be substituted into the equation
x - 2 + 16 = 2y
2y = x - 2 +16
2y = x + 14
Divide both sides by 2
y = x/2 + 14/2
This is the equation in slope-intercept form
where the slope = 1/2
Answer:
Nico's solution is correct
Step-by-step explanation:
Lorena introduced a spurious minus sign in the denominator in the next-to-last step, so ended up with a result that has the wrong sign.
