Pavlova-9 [17]

Answer:

y=2x+3

Step-by-step explanation:

first use the y2-y1/x2-x1 then use y=mx+b after

plug in 3 for y2 and 5 for y1

then plug in 0 for x2 and 1 for x1

\frac{3-5}{0-1}=\frac{-2}{-1} =2 and 2 is ur slope

now use y=mx+b

i usually use the first point but u can u anyone u want

plug in 1 for x

5=2+b

subtract 2 on both sides

5-2=3

3=b and b is ur y-intercept

y=2x+3
