What is the y-intercept in the equation y=45x+65

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.
