Answer:
(a) (-1/4,0)
(b) k = (10-c)/2
Step-by-step explanation:
(a) A point passing through the y-axis is the same as finding the y-intercept.
[Move terms to right-hand side; y = mx + b form]
y = 4x + 1
[Find x, when y = 0]
0 = 4x + 1
-1 = 4x
-1/4 = x
At x = -1/4, y = 0 therefore the point: (-1/4,0) crosses the y-axis.
(b) To find the value of k in (k,10), we need to find x. Given y= 10 x=k c=constant
[Find x by plugging in known values]
Using y = 2x + c,
10 = 2k + c
10 - c = 2k
(10-c)/2 = k
