Answer:
y = (7/2)x - 2
Explanation:
Use slope-intercept formula for linear equations y = mx + b
x and y show what points are on the line. We know (4, 12). x= 4 and y = 12
b is the y-intercept, which b = -2.
m is the slope.
To write the equation, you need the slope and y-intercept. Find the slope by putting x, y and b into the formula.
y = mx + b
12 = 4m - 2
14 = 4m
14/4 = m
m = 7/2
Put "m" into the formula with "b"
y = (7/2)x - 2
