Answer:
y-4 = -2(x+1)
Step-by-step explanation:
The point-slope equation of a line is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
You have m = -2 and (h, k) = (-1, 4). Putting these numbers into the above form gives ...
y -4 = -2(x +1)
0.7 is seven tenths.
Seven tenths as a fraction is 7/10.
Hope this helps!
Answer:
Step-by-step explanation:
- We must prove that : sin²∝ + sin²∝ × tan²∝ = tan²∝
- sin²∝+ sin²∝× tan²∝ = sin²∝(1+tan²∝)
- 1+ tan²∝= 1/cos²∝
- So: sin²∝(1+tan²∝)= sin²∝/cos²∝ =tan²∝
Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
