Step-by-step explanation:




Y2-y1/x2-x1 = 7-8/-3-4=-1/-7 =1/7
Answer:
slope: -2, y- intercept: 7
Step-by-step explanation:
put in the form y = mx + b, where m = slope and b = y-intercept
2x + y = 7
subtract 2x from both sides
y = -2x + 7
m = -2, b = 7
We'll use the Pythagorean Theorem (otherwise known as the Distance Formula):
Going from Q to P, x increases by 1 and y increases by 7. Thus, the component form of QP is <1,7>, and the magnitude of this vector is √(1^2+7^2) = 5√2.
Note: this is equivalent to <1, 7>, square root of 50.
Answer:
3 x $10.50 = $31.50
Step-by-step explanation:
$10.50 + $10.50 + $10.50 = $31.50
$10.00 + $10.00 + $10.00 = $30.00
$0.50 + $0.50 + $0.50 = $1.50
$30.00 + $1.50 = $31.50
