A line passes through the point (9,-7) and has a slope of 4/3

lara31 [8.8K]

Answer:

y+7 = 4/3(x-9)

Step-by-step explanation:

Point slope form of an equation of a line is

y-y1 = m(x-x1) where (x1,y1) is the point and m is the slope

y--7 = 4/3(x-9)

y+7 = 4/3(x-9)

How many solutions does this system have?

goblinko [34]

A system of equation may have one, zero or infinitely many solutions

The system of equation has no solutions

The systems of equation are given as:

$y = -6x - 5$

$-2y +7 = 12x$

Substitute -6x - 5 for y in $-2y +7 = 12x$

$-2(-6x - 5) +7 = 12x$

Open brackets

$12x + 10 +7 = 12x$

$12x + 17 = 12x$

Subtract 12x from both sides of the equation

$17 = 0$

The above equation is not true i.e. $17 \ne 0$

Hence, the system of equation has no solutions
