Find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=-3/4x-3

The equation of the line would be y = 4/3x - 1

Step-by-step explanation:

In order to find the equation of this line, we first have to note that perpendicular lines have opposite and reciprocal slopes. Therefore, since the original line has a slope of -3/4, we know the new line will have a slope of 4/3. Now we can use that information along with the given point in point-slope form to find the equation.

y - y1 = m(x - x1)

y + 1 = 4/3(x - 0)

y + 1 = 4/3x

y = 4/3x - 1

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
