(3, -5)(0, 4)<br> Write the equation of a line using the point slope formula
Serga [27]

Answer:

y = - 3x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (0, 4)

m = \frac{4-(-5)}{0-3} = \frac{4+5}{-3} = \frac{9}{-3} = - 3

The line crosses the y- axis at (0, 4) ⇒ c = 4

y = - 3x + 4 ← equation of line

If 5% of an amount equals 800,000, then what is that amount? Please I confused, can someone help me!
kondor19780726 [428]

Answer:

the amount is 16,000,000

Step-by-step explanation:

first let that amount be Y for an example. so...

\frac{5}{100}*Y=800,000

\frac{5Y}{100}=800,000

5Y=800,000*100

5Y=80,000,000  (then you both divide by 5 in both sides so that Y is left alone.)

So      Y=16,000,000

so the amount you are looking for is 16,000,000

write the equation of a line in slope intercept form that passes through (2 -2) and is parallel to 2x+4y=8
Ne4ueva [31]

Answer:

y= -1/2x-1

Step-by-step explanation:

1) put the equation in y-intercept form to find the slope of the original line 2x+4y=8

y=8/4-2x/4

y=2-1/2x

slope of second line will be -1/2

2) put point into the point-slope form (2,-2)

y-(-2)= -1/2(x-2)  now simplify

y+2= -1/2x+2/2

y+2 = -1/2x + 1

y+2-2=-1/2x + 1 -2 ====>>>>  y= -1/2x-1
