Step-by-step explanation:
Step-by-step explanation:
△BAC ≅ △EDF (given)
Therefore,
BC=EF
x-4=19
x=23
Answer:y=8x
Step-by-step explanation:
The point-slope form:

We have the point (1, 6) and the slope m = 7/3. Substitute:
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>multiply both sides by 3</em>
<em>subtract 7x from both sides</em>
<em>change the signs</em>

Answer:
point-slope form: 
slope-intercept form: 
standard form:
