Problema Solution
write the equation in standard form and find slope
y=2x+3
Answer provided by our tutors
"standard form" means the form "Ax + By + C = 0" where A, B, and C are all whole numbers and A is positive
y = 2x + 3
2x - y + 3 = 0 is the standard form
the slope m = (y2 - y1)/(x2 - x1) where y2 = 2*x2 + 1 and y1 = 2*x1 + 3
y2 - y1 = 2*(x2 - x1)
m = 2*(x2 - x1)/(x2 - x1)
m = 2
the slope is 2.
