The equation of a straight line AB is y = -2x - 11.

The x-intercept of the line is .

Solution:

Given data:

C(-2, 0) and D(0, -4)

Slope of CD:

m = -2

AB and CD are parallel lines.

If two lines are parallel then their slopes are equal.

Therefore slope of AB = -2

AB passes through the point (-3, -5).

Point-slope formula:

Here, m = -2 and

y - (-5) = -2(x - (-3))

y + 5 = -2(x + 3)

y + 5 = -2x - 6

Subtract 5 on both sides, we get

y = -2x - 11

The equation of a straight line AB is y = -2x - 11.

To find the x-intercept,substitute y = 0 in the equation of a line.

0 = -2x - 11

Add 11 on both sides.

11 = -2x

Divide by -2 on both sides.

The x-intercept of the line is .

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
