Write the slope-intercept form equation of a line that goes through the point (4, -4) and is parallel to y = -7x + 5.

Answers

Answer 1

Answer:

y=7x-32

Step-by-step explanation:

Since the line is parallel to y=-7x+5, it will have the same slope

use the slope-intercept form to find b, y=7x+b

plug the points into the equation

(-4)=7(4)+b

simplify

-4=28+b

subtract 28 from both sides

b= -32

plug b into the equation

y=7x-32

The equation of line L is 2x+y=3

Line M is parallel to line L and passes through
(1,−6)

Work out the equation of line M.
Give your answer in the form
y=ax+b

(3 marks)

Answers

Answer:

y = -2x - 4

Step-by-step explanation:

We transform the line equation of L:

2x + y = 3 --(-2x)--> f(x) = y = -2x + 3

We now know that L intersects the y-axis at 3 and it has a slope of -2.

In order to construct a parallel line M, it needs to have an identical slope to L.

All we need to do now is to move one step from the given point (1,-6) towards 0 with the predetermined slope of -2, resulting in the point (0,-4).

Since we know slope and intersection with the y-axis (0,-4), we can construct the line equation:

f(x) = y = -2x - 4 for line M.

S=32t C. S=32-t D. s=t+32​

Answers

Answer:

B. s = 32t

Step-by-step explanation:

The equation would be in the form of s = mt.

Where, m = rate of change

Find rate of change using any two values given in the table, say (1, 32) and (2, 64)

Rate of change (m) = ∆s/∆m = (64 - 32)/(2 - 1) = 32/1 = 32

✔️To write the equation, substite m = 32 into s = mt

s = 32t

x + 3y = 1
5x +6y = 14

Answers

Answer:

1. X = 1 - 3y

2. -5/6x + 7/3

Those are the answers to the problems

(x,y) = (4,-1)

x + 3y = 1 subtract 5 from both sides you get -5x -15y =-5

now sum it up
-5x -15y =-5
5x +6y = 14
you get -9y = 9
divide both sides by -9

you get y=-1

NOW substitute y for x + 3 times (-1)= 1

solve for x and get x=4

therefore your answer is (4,-1)
