Step-by-step explanation: The y-intercept is where the line on a graph crosses the y-axis. For example Y=2x-2. The line crosses the y-axis at (0,-2). So the Y-intercept would be (0,-2)
When we look at Y=mx+b (slope intercept form)
M being the slope and B being the Y intercept.
So to write it as an ordered pair you just need to put 0 in place of the x-coordinate. So (0,-2)

Question
---------------------------------------------------
x² - 49
--------------------------------------------------
Form into 2 perfect squares
---------------------------------------------------
x² - 7²
--------------------------------------------------
Formula
---------------------------------------------------
a² - b² = (a + b) (a - b)
--------------------------------------------------
Apply the formula
---------------------------------------------------
x² - 7² = (x + 7)(x - 7)
--------------------------------------------------
Answer: (x + 7)(x - 7)
---------------------------------------------------
Step-by-step explanation:
2vt= (ht²/2) - 2c - r
v= ((ht²/2) -2c -r) / 2t
v= ht/4 - c/t - r/2t
