A line intersects the point (0,-11) and has a slope of 0. What is the slope-intercept equation for this line?

True [87]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept → (0, b)

We have the slope m = 0 and the point (0, -11) → b = -11.

Substitute:

y = 0x - 11 = -11

It's a horizontal line.

Ben is 20 years older than Daniel. Ben and Daniel first met two years ago. Three years ago, Ben was 3 times as old as Daniel.How

astraxan [27]

Let $b=$ Ben's age
Let $d=$ Daniel's age

We know:
$b=d+20$
and
$b-3=3(d-3)$

Plug the value of $b$ into the second equation:
$(d+20)-3=3(d-3)$
$\rightarrow d+17=3d-9$
$\rightarrow-2d+17=-9$
$\rightarrow-2d=-26$
$\rightarrow d=13$

Since Ben is 20 years older than Daniel, Ben is 13+20=33 years old.
