begin by solving the linear equation for y. This will put the equation in slope-intercept form. Then find the slope and the y-intercept of the line with this equation. 3x - 4y = 12
It says to solve the equation for y first.
3x - 4y = 12 : Start by subtracting 3x from both sides
-4y = -3x + 12 : Then divide both sides by -4
y = 3/4x - 3 : Dividing the -3 by -4 it became a positive and 12/-4 is negative 3.
The equation is now in slope-intercept form. The next part of the question said to figure out the slope and the y-intercept of the line using this equation.
Slope-intercept form is y = mx + b
m = slope (3/4)
b = y-intercept (-3)
