Slope = 4/3, (-2, 11)

Lady_Fox [76]

Answer:

y = $\frac{4}{3}$ x + $\frac{41}{3}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = $\frac{4}{3}$ , hence

y = $\frac{4}{3}$ x + c ← is the partial equation

to find c substitute (- 2, 11) into the partial equation

11 = - $\frac{8}{3}$ + c ⇒ c = $\frac{41}{3}$

y = $\frac{4}{3}$ x + $\frac{41}{3}$ ← equation of line

Evaluate the expression if r = 12 and t = -6.<br> (t-r)/3

Lynna [10]

Answer:

-6

Step-by-step explanation:

$\frac{(t-r)}{3}$

input the numbers

$\frac{(-6-12)}{3}$

do the problem in the parentheses first

-6-12 = -18

now it becomes

$-\frac{18}{3}$

simplify and you'll get

-6

this is because -18 ÷ 3 =
