A. (-3,5)(0,7)
slope = (7 - 5) / (0 - (-3) = 2/3
y = mx + b
slope = 2/3
(0,7)...x = 0 and y = 7
sub and find b, the y int
7 = 2/3(0) + b
7 = b....this is ur y int (0,7)
so ur equation for this line is : y = 2/3x + 7
b. (6,2)(9,4)
slope = (4 - 2) / (9 - 6) = 2/3
y = mx + b
slope(m) = 2/3
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 2/3(6) + b
2 = 4 + b
2 - 4 = b
-2 = b...this is ur y int (0,-2)
so this equation is : y = 2/3x - 2
so " a " has a slope of 2/3 and a y int of 7 and " b " has a slope of 2/3 and a y int of -2.
ur lines are parallel lines.....parallel lines will have the same slope and different y intercepts <===
Answer:
1) 29/5
2) 17/5
Step-by-step explanation:
Answer:
Step-by-step explanation:
If a point is dilated by a scale factor 'k' centered at the origin,
Coordinates of the image point becomes as,
(x, y) → (kx, ky)
By this rule,
Coordinates of the vertices of the image triangle, when preimage is scaled by a factor of 5 about the origin will be,
T(-1, -2) → T'(-5, -10)
U(2, -2) → U'(10, -10)
V(-1, 1) → V'(-5, 5)
Answer:
a.-11 . b.11
Step-by-step explanation:
6x-17= -11 . 4x+7= 11
Answer:
-12 feet per second
Step-by-step explanation:
average rate of change over [0.75, 1.25] =
f(1.25) - f(0.75) = 4 - 10 = -6
1.25 - 0.75 = 0.5
= = -12
