A line with slope 2 passes through the point (2, -4). Find the coordinates of another point on the line.​
Brilliant_brown [7]

Answer:

(3, -2)

Step-by-step explanation:

 We can view slope as: \frac{rise}{run} (rise / run)

"rise" is the change in y from one point to another

"run" is the difference in x from one point to another

So, if the slope of a line is 2, it rises 2 every time it runs 1 (2 = 2/1)

So, we can find another point on the line by adding 2 to the y-value, and adding 1 to the x-value.

(x, y)  

          (2, -4)

         + 1  + 2

           (3, -2)

So, another point on this graph is (3, -2)

Please help me!!!!!!!! Factor z2 – 3z – 18
Vladimir [108]
First, the factor pairs for 18 are:
1, 18
2, 9
3, 6

Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3

Set each equal to 0;
z = -6
z + 6 = 0

z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.

PLEASE HELP
Colt1911 [192]

Answer:

B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.

Step-by-step explanation:

A is being moved to the other side of the equation so it has to be negative and is multiplied by B since the y value has to be divided to equal the base of y not 9y but y.

Write the slope-intercept of the equation through the points (2,5)and perpendicular to the line y=-1/2x+7
AleksandrR [38]

Answer: y=1/2x+4

Step-by-step explanation:

1. y-y1=m(x-x1)

2.y-5=1/2(x-2)

3. solve

4. y-5=1/2x-1

5. add 5 to both sides to isolate the variable

6. this gives you y=1/2x+4

PLEASE HELP ME WITH THIS QUESTION FOR MATH!!!!!!!!!!!!!!!!!
kozerog [31]

Answer:

MON = 130°

Step-by-step explanation:

LOM + MON = 180°

In other words

4z + 30° + 8z + 90 = 180°

12z + 120 = 180

60 = 12z

z = 5

5 x 8 = 40 + 90 = 130°
