Answer:
y = -
x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
=
= - 
Since the line crosses the y- axis at (0, 6) ⇒ b = 6
y = -
x + 6 ← equation of line
A= 72.5 (you take 145 and divide by 2 b/c one inside is smaller)
B= 72.5 also b/c the share a corresponding line
Answer:
x^2+8x+15
Step-by-step explanation:
You can use FOIL method
(x*x)+(x*5)+(3*x)+(3*5)
x^2+5x+3x+15
x^2+8x+15
The answer is the first and third one
Answer:
Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)
Step-by-step explanation:
m=3 , x1=1 , y=-3
y-(-3)=3(x-1)
y+3=3x-3 subtract 3 from both sides
y=3x-6 the answer in the slope-intercept form y=mx+b
