Answer:
Step-by-step explanation:
Consider the answer choices.
3 & 5: product 15, sum 8 . . . . product > sum
2 & 2: product 4, sum 4 . . . . product = sum (not >)
1 & 4: product 4, sum 5 . . . . product < sum (not >)
Of the offered choices there are two counter examples:
2 and 2
1 and 4
_____
<em>Additional comment</em>
Chances are that the preferred answer is 1 and 4.
1 and <anything> will be a counterexample.
Answer:
x = -1
Step-by-step explanation:
Because the line passes through two points that both have the same x value, this means the line is vertical, and the slope is undefined.
So the equation of the line is x = -1.
Answer:
y = 5x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, then
y = 5x + c ← is the partial equation
To find c substitute (1, 9) into the partial equation
9 = 5 + c ⇒ c = 9 - 5 = 4
y = 5x + 4 ← equation of line
