Answer:
Equation is in the standard dorm.
Step-by-step explanation:
Here, the x - intercept = 4 , so ( 4,0) is a point on the line.
and the y - intercept = 5, so ( 0,5) is a point on the line.
So, the slope of the equation is given as =
Now, the SLOPE INTERCEPT FORM of an equation is :
y = mx + b: here m = slope and b = y- intercept
or,
Now, standard form is Ax +By = C
So, the standard form is
Hence, the above equation
is in the standard dorm.
Let's solve for x:
100x=1000
Divide by 100
x=10
You should expect to win 10 times.
