To write the equation, we will first need to find the intercept
To find the intercept, substitute x= 3 y=7 m = 7 into
y =mx + b and then solve for b
where m is the slope and b is the intercept
7 = 7(3) + b
7 = 21 + b
subtrcat 21 from both-side of the equation
7 - 21 = b
-14 = b
b = -14
To form the equation, simply substitute; m = 7 and b = -14
into y =mx + b
Hence, the equation is :
y = 7x - 14
