(-4)^2-4x(-10)x2=96
Answer:
m = -2/3 and b = -1/3
Step-by-step explanation:
Write the equation of this line in slope-intercept form. Then m = slope and b = y-intercept and the basic equation is y = mx + b.
Solving 3y+2x=-1 for y, we get 3y = -2x - 1, or y = (-2/3)x - 1/3
Here we can easily see that m = -2/3 and b = -1/3.
