Hi there!
Point-slope form: where <em>m</em> is the slope and
is a point that falls on the line
Plug in the slope, -6/7, and the given point, (1,2):
To write the equation in slope-intercept form, isolate y:
I hope this helps!
Answer:
The roots are:
and 
Explanation:
First, we would need to put the equation is standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
4x² - 12x + 9 - 3 = 0
4x² - 12x + 6 = 0
By comparison, we would find that:
a = 4
b = -12
c = 6
To get the roots, we would substitute in the quadratic formula shown in the attached image.
Doing this, we would find that:
either x =
or x =
