Reil [10]

Y is 12. X is 2 and if you add 12 plus 2 it makes 14. and 12 minus 5 times 2 equals 2

The slope of the line below is 2. Use the coordinates of the labeled point to find a point-slope equation of the line.
stich3 [128]

Answer:

Option: D is the correct answer.

The equation of line in point-slope form is given by:

y-9=2(x-1)

Step-by-step explanation:

We know that the point-slope equation of a line is given by:

y-b=m(x-a)

where (a,b) is the point from which the line passes and m is the slope of the line.

Here we are given that:

The line passes through (1,9) and slope of the line is given to be 2.

Hence,

(a,b)=(1,9) and m=2

Hence, the equation of line is given by:

y-9=2(x-1)

Therefore, the point slope intercept equation of the line is: D

Solve.<br> 2a + 4 &gt; 12<br> {ala &gt; 2}<br> {ala &gt; 4}<br> {ala &gt; 8}<br> {ala &gt; 10}
Softa [21]

Answer:

b)   a > 4

Step-by-step explanation:

<u>Step(i)</u>:-

Given inequality equation

                              2 a + 4 > 12

subtracting ' 4' on both sides , we get

                              2 a + 4 -4 > 12 -4

                               2 a > 8

<u><em>Step(ii)</em></u>:-

dividing '2' on both sides , we get

                             \frac{2a}{2} > \frac{8}{4}

                             a > 4
