I need help with this, I tried it and I don’t get it, can u just help me and explain please!

10-11 write a the slope-intercept form of the line with the given slope and point.10. m=4;(2,3)11. m=-2;(5,1)

The formula for slope intercept form is y = mx + b, where m represents the constant and b represent the y-intercept.

10. We know m is equal to 4. So let’s plug that into the equation.

y = 4x + b.

We are given the point (2, 3), so let’s plug that in and solve for b.

(2 is x and 3 is y)

3 = 4(2) + b

3 = 8 + b    Subtract 8.

-5 = b.

The equation is y = 4x – 5

11. We know m is equal to -2. So let’s plug that into the equation.

y = -2x + b

We are given the point (5, 1), so let’s plug that in and solve for b.

1 = -2(5) + b

1 = -10 + b     Add 10.

11 = b

The equation is y = -2x + 11

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
