Step-by-step explanation:
The slope m of the line = tan45° = 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1 , then
y = x + c
To find c substitute (2, 1 ) into the equation
1 = 2 + c ⇒ c = 1 - 2 = - 1
y = x - 1 ← equation of line
When x = 0 then y = 0 - 1 = - 1
The line passes through (0, - 1 )
Answer:
28
Step-by-step explanation:
V = 4 * 1 * b = 8
b = 2
SA = 2(4 + 1) * 2 + 2(4)1)
SA = 28
