Answer:

y = -2x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Points: (3, 4)

Slope: -2

y = -2x + b

4 = -2 ( 3 ) + b

4 = -6 + b

b = -2

y = -2x - 2

Answer:

y = -2x + 10

Step-by-step explanation:

To find the equation y=mx+b

The slope is already given so plug it in

y = -2x + b

Then your given a point so plug that into the equation to find b

y=4

x=3

4 = -2(3) + b

4 = -6 + b

+6 +6

10 = b

then plug everything in and your equation is y = -2x + 10

hilton university drama club sold 311 tickets for a play. student tickets cost 50 cents each,nonstudent tickets cost $1.50. if t

tamaranim1 [39]

X= number of student tickets

Y= number of on student tickets

x+y=311

0.50x + 1.50y = 385.50

Solve x in 1st equation

X+y=311

X= -y + 311

Now substitute x into second equation to solve for y

0.50(-y+311)+ 1.50y = 385.50

-0.50y+311.50+1.50y=385.50

Y+311.50=385.50

Y= 385.50-311.50

Y= 74

Now substitute y answer to first equation to find x

X+y=311

X+ 74=311

X= 311-74

X= 237

So 237 students tickets and 74 non students tickets

Find the slope of a line that passes through the following points (-1,-5), (3,-3)

svet-max [94.6K]

Answer:

$m=\frac{1}{2}$

Step-by-step explanation:

defition of slope(m) of a line:

$m=\frac{Y_b-Y_a}{X_b-X_a}$

A=(-1,-5)=(Xa,Ya) then Xa= -1 and Ya= -5

B=(3,-3)=(Xb,Yb) then Xb=3 and Yb= -3

$m=\frac{-3-(-5)}{3-(-1)} \\\\m=\frac{-3+5}{3+1} \\\\m=\frac{2}{4} \\\\m=\frac{1}{2}$
