Answer:
65
Step-by-step explanation:
hello
The linear function is defined by the equation f (x) = mx + b or y = mx + b called the canonical equation, where m is the slope of the line and b is the intercept with the Y axis
step 1
compare the equations
y=45x +54 and y=mx+b
we can deduce
m=45 and b=65
b is the intercept with y axis
so intercept is 65
step 2
additionally we can check it by doing x = 0, when x = 0 is when the line intercepts the y axis
y(0)=intercept
Y(0)=45(0)+65
y(0)=65= intercept
so intercept is 65
Have a great day.
