Do anybody know this?

y = 2x + 4

Step-by-step explanation:

find slope with m = (y2 - y1) / (x2 - x1)

I used ( 0,4) and (-2,0)

so (4 - 0)/(0 - (-2))

which is 4/2 or 2

then find y intercept by using a test point (I used 0,4)

so y = 2x + b, 4 = 2 (0) + b, 4 = b

Final: y = 2x + 4

what "following statement"?

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

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

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
