Answer:
y = -4/5x - 4
Step-by-step explanation:
y - y1 = m(x-x1)
4x + 5y = 20 ( subtract 4x on both sides)
5y = -4x + 20 (divide by 5 on each side)
y = -4/5x + 4
So we know one point is (0,4) y-intercept
now plug in (0,4)
y - 4 = -4/5(x-0) (Distribute -4/5 to x - 0)
y - 4 = -4/5x (now add 4 on each side)
y = -4/5x - 4
Answer:
y = [tex]-\frac{4}{5}[/tex] x + 4
Step-by-step explanation:
Ax + By = C is standard form of linear equation.
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
y = mx + b is slope intercept form of linear equation.
Thus, to write the point-slope equation we have to have the coordinates of the point that given line is passing through!
I assume, that we have to re-write the standard form of linear equation into slope-intercept form. That's mean, we have to solve given equation for "y".
5y = - 4x + 20
y = [tex]-\frac{4}{5}[/tex] x + 4
