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
You could set up a proportion to figure out the anwer. 15 hurdles/60%=X hurdles/100%. Cross multiply, 1500=60x. Divide by 60, 25=X=total amount of hurdles. Hope this helps!
