Write the equation of the line in fully simplified slope-intercept form.

PtichkaEL [24]

Answer:

Consider points (0, -5) and (-6, -1)

» General equation of a line:

${ \tt{y = mx + c}}$

m is slope
c is y-intercept

 Slope (m):

${ \tt{m = \frac{ - 1 - ( - 5)}{ - 6 - 0} }} \\ \\ { \tt{m = \frac{4}{ - 6} }} \\ \\ { \tt{m = - \frac{2}{3} }}$

 y-intercept (c):

${ \tt{y = mx + c}}$

consider point (0, -5)

${ \tt{ - 5 = c}} \\ { \tt{c = - 5}}$

Equation:

${ \boxed{ \tt{y = - \frac{2}{3} x - 5}}}$

Solve the equation by factoring.

Delicious77 [7]

Factorizing an expression involves writing the expression in simpler forms

The values of z are $z = \frac 15$ or $z=4$

The equation is given as:

$5z^2 - 21z + 4 = 0$

Expand the equation

$5z^2 - 20z -z + 4 = 0$

Factorize the expression:

$5z(z - 4) -1(z - 4) = 0$

Factor out z - 4

$(5z - 1)(z - 4) = 0$

Split

$5z -1 = 0$ or $z - 4 = 0$

Solve for z

$z = \frac 15$ or $z=4$

Hence, the values of z are $z = \frac 15$ or $z=4$
