Answer:
Step-by-step explanation:
a) While line crosses y axis, x = 0
Plugin x = 0 in the equation
y - 4*0 = 1
y = 1
(0 , 1)
b) line passes through the point (0, -3)
y = 2x + c
-3 = 2*0 + c
-3 = c
Equation: y = 2x - 3
y=2x -3 passes through (k,10)
10 = 2*k - 3
10 = 2k - 3
10 + 3 = 2k
13 = 2k
13/2 = k
k = 6.5
