Using point slope formula, y- y1 = m(x - x2)
y - -7 = -3( x - 5)
y + 7 = -3(x - 5)
If the answer needs to be in slope intercept form multiply the -3 by x and -5
y + 7 = -3x +15
Subtract 7 from both sides
y = -3x + 8
Answer:
x = 8
y = -7
Step-by-step explanation:
3y - 5x = -61
-----------------------+
-9x = -72
x = 8
3y -5(8) = -61
3y - 40 = -61
3y = -21
y = -7
Answer:
x = 8√2
Step-by-step explanation:
Use Pythagorean Theorem to solve for x.
x² + x² = 16²
⇒ 2x² = 256
⇒ x² = 128
⇒ x = 8√2
