Answer:

y= 2x +7

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is 2, m=2.

y= 2x +c

Given that the y-intercept is -7, c = -7.

y= 2x +7

Point m is the midpoint of ab¯¯¯¯¯ . am=3x+3, and ab=8x−6. what is the length of am¯¯¯¯¯¯ ?

LuckyWell [14K]

As given m is a midpoint of ab. So am is half of ab.

So we can write

$am = \frac{ab}{2}$

As given am = 3x+3 , ab = 8x - 6.

So $3x+3 = \frac{8x - 6}{2}$

$3x+3 = \frac{2(4x - 3)}{2}$

$3x+3 = 4x - 3$

$3+3 = 4x - 3x
$

$6 = x$

So x = 6.

So length of am = 3x+3 = 3*6 + 3 = 21
