Answer:
y = x + 3
Step-by-step explanation:
The equation of a line is y=mx + b, where m is the slope and b is the y-intercept.
In this case, the slope of the line is 1, and the y-intercept (the point where the line crosses the vertical axis) is 3. So you just need to plug in the 3 in place of b.
y = mx + b
m = 1
b = 3
y = x + 3
The answer to your question is x=-1
Answer:
C) -4
Step-by-step explanation:
this is correct as far as i know.
Answer:
y = 4x² - 4
Step-by-step explanation:
y = a(x - x₁ )(x - x₂)
Plug in the knowns
y = 4(x - 1)(x + 1)
expand
y = 4(x² - 1)
y = 4x² - 4
