What is the equation of a line that passes through (7, 8) and has a slope of -3?
a.
`y = -3x + 29`
select the correct answer from each drop-down menu.
points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of δabc is 180°.
statement reason
points a, b, and c form a triangle. given
let be a line passing through b and parallel to . definition of parallel lines
∠3 ≅ ∠5 and ∠1 ≅ ∠4
m∠1 = m∠4 and m∠3 = m∠5
m∠4 + m∠2 + m∠5 = 180° angle addition and definition of a straight line
m∠1 + m∠2 + m∠3 = 180° substitution
b.
`y = 3x + 13`
c.
`y = (1)/(3)x− 29`
d.
`y = -(1)/(3)x− 13`

A. `y = -3x + 29`

Step-by-step explanation:

The equation of a line is expressed as y = mx + c where m is the slope of the line and c is the intercept.

The slope of the line is given as -3.

So the equation can be represented as y = -3x + c

The line passes through point (7,8)

=> 8 = -3(7) +c

=> 8 = -21 + c

=> c = 8 + 21 = 29

Substituting in the original equation of the line:

y= -3x + 29

Validation: Substituting x= 7 and y=8 in the equation:

8 = -3 * 7 + 29

Or 8 = 8

So the two sides are equal and our equation is valid.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
