Answer:
The equation of the line is
Step-by-step explanation:
Looks like you've already found the y-intercept and slope of this graph. Great! That's all the info we need to create an equation.
The equation of a line is always in form, where k is the constant of proportionality (aka the slope) and b is the constant added (aka the y-intercept).
We know the slope is 3 and the y-intercept is 3, so we can put these values into the equation.
Hope this helped!
We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0
so
given
5x^2-6x+2=0
a=5
b=-6
c=2
