The equation of line AB is y = 5x + 1. Write an equation of a line parallel to line AB in slope-intercept form that contains poi

nt (4, 5).
y = 5x − 15
y = 5x + 15
y = 1 over 5x + 21 over 5
y = 1 over 5x − 29 over 5

Y = 5x + 1....the slope here is 5...a parallel line will have the same slope.

y = mx + b
slope(m) = 5
(4,5)....x = 4 and y = 5
now we sub and find b, the y int
5 = 5(4) + b
5 = 20 +b
5 - 20 = b
-15 = b

so ur parallel line is : y = 5x - 15

A line has a slope of 2/3 and a y-intercept of −5. Which equations represent the line? Choose all answers that are correct. (MUL
marin [14]
A.         -2x + 3y = -15
    -2x + 2x + 3y = 2x - 15
                     3y = 2x - 15
                      3          3
                       y = ²/₃ - 5
A is correct.

B. y = ²/₃ - 5
B is also correct.

C. 6y = 4x - 30
     6           6
       y = ²/₃x - 5
C is also correct.

D. y + 3 = ²/₃(x - 3)
     y + 3 = ²/₃(x) - ²/₃(3)
     y + 3 = ²/₃x - 2
         - 3          - 3
           y = ²/₃x - 5
D is also correct.

The answer to the problem is A, B, C, and D.

The value of x varies directly with y, and whenX= 2/3, y = 6. Find the value of y when x = 10-24A.y=9B.y=4C. y=93D.y=1
uysha [10]

Problem

Solution

for this case we know that when x =2/3 , y= 6

10\frac{1}{3}=\frac{10\cdot3+1}{3}=\frac{30+1}{3}=\frac{31}{3}

Then we want to find the value of y= ? when x= 10 1/3 = 31/3 and we can do this:

6/(2/3) = y/(31/3)

\frac{6}{\frac{2}{3}}=\frac{y}{\frac{31}{3}}y=\frac{31}{3}\cdot\frac{6}{\frac{2}{3}}=\frac{31}{3}\cdot\frac{3}{2}\cdot\frac{6}{1}=\frac{31\cdot3\cdot6}{3\cdot2\cdot1}=93

And solving for y we got:

y = (3/2) * 6 * (31/3) = 31*3 = 93

C. y= 93
