The answer is C because it’s the only answer that could be correct.
Answer:
The constant rate of change is 1.5
The point that intersects the y axis is (0,0)
Step-by-step explanation:
Constant rate of change: y2-y1/x2-x1
(1,1.5) (2,3)
3-1.5=1.5
2-1=1
1.5/1=1.5
Constant rate of change is 1.5
Hope this helps!
C. y = 3x - 4
Step-by-step explanation:
Given coordinates:
(2, 2), (3, 5), (5, 11), (7, 17)
The equation of any straight line is
y = mx + c
Where
m = Gradient
c = Constant
Gradient = y2 - y1/x2 - x1
Substitute any two values of y with the respective values of x.
Gradient = 17 - 2/7 - 2
= 15/5
= 3
Substitute the gradient into the general formula.
y = 3x + c
Substitute any value of the coordinate to the equation
2 = 3(2) + c
2 = 6 + c
c = -4
From y = mx + c,
substitute the values of m, the gradient, and c, the constant.
y = (3)x + (-4)
y = 3x - 4
