The point-slope form of the equation of the line that passes through (-4,-3) and (12, 1) is y-1= 164–12). What is the standard form of the equation for this line?​

Answer:


y = (1)/(4)x -2

Explanation:

Step 1: Find the standard form of the equation

The equation that was given made no sense so I will recreate the entire equation using the point slope formula.

Use the point slope formula


y - y_(1) = m(x - x_(1))


y - (-3) = m(x - (-4))


y +3 = m(x + 4)

Find the slope


m = (y_(2)-y_(1))/(x_(2)-x_(1))


m = (1-(-3))/(12-(-4))


m = (1+3)/(12+4)


m = (4)/(16)


m=(1)/(4)

Combine them together


y +3 = (1)/(4)(x + 4)

Convert to standard form


y +3 = (1)/(4)x + 1


y +3 - 3 = (1)/(4)x + 1 - 3


y = (1)/(4)x -2

Answer:
y = (1)/(4)x -2
