QUESTION 1i)

The given equation passes through

(3,11) and (-2,1).

The slope of the line is

$m = \frac{11 - 1}{3 - - 2}$

$m = \frac{10}{5}=2$

The equation is given by

$y-y_1=m(x-x_1)$

We can use any of the given points.

$y - 1 = 2(x - - 2)$

$y = 2(x + 2) + 1$

$y = 2x + 4 + 1$

The equation is

$y = 2x + 5$

QUESTION 1ii)

A point that lies on this line must satisfy the equation of this line.

We can choose any value for x and substitute to find the corresponding y-value.

When x=0,

$y = 2(0) + 5 = 5$

Therefore, the point (0,5) lies on this line.

QUESTION 1iii)

The point (0,6) does not lie on this line.

We can verify this by substituting (0,6) into the equation of the line.

$6 = 2(0) + 5$

$6 = 5$

This statement is false.

QUESTION 2

The line passes through, (0,4) and (2,0).

The slope of this line is

$m = \frac{4 - 0}{0 - 2} = - 2$

The equation of this line is

$y - 0 = - 2(x - 2)$

$y = - 2x + 4$

We substitute the point (-25,81) to determine whether this point lies on this line.

$81 = - 2( - 25) + 4$

$81 = 104$

This is a false statement.

The point (-25,81) does not lie on this line.

How do i solve this equation: 15-g=23-2g

motikmotik

You would move the variables to one side and numbers to the other, so move -2g to the other side to make it positive. That leaves you with g+15=23. Now move 15 to the other side which means it will be negative so subtract 15 from 23 which gives you 8. g = 8

Someone please help this is so confusing

Sphinxa [80]

Answer:

a is 10

Step-by-step explanation:

parallel lines have the same slope, but a different y intercept

you would substitute the ordered pair in for x and y

y=-2x+10

Hope this helps :-)

the difference between seven times one number and three times a second number is 25. The sum of twice the first and five times t

inysia [295]

$\left \{ {{7*x - 3*y=25} \atop {2*x + 5*y=95}} \right.$

$\left \{ {{7x - 3y=25}(I) \atop {2x + 5y=95}(II)} \right.$

$\left \{ {{7x - 3y=25}simplify*(5) \atop {2x + 5y=95}simplify*(3)} \right.$

$\left \{ {{35x - \diagup\!\!\!\! 15 y=125} \atop {6x + \diagup\!\!\!\! 15y=285}} \right.$

$\left \{ {{35x =125} \atop {6x =285}} \right.$

$41x = 410$

$\boxed{x=10}$

Replace the value of "x" in the second equation (II) to find the value of "y", thus:
 $2x + 5y=95$
$2*(10)+5y = 95$
$20+5y=95$
$5y=95-20$
$5y=75$
$y = \frac{75}{5}$
$\boxed{y=15}$

The numbers (10,15)
