Answer:
x=2
Step-by-step explanation:
-3x+7=1
subtract 7 from both sides: -3x+7-7=1-7
simplify: -3x=-6
divide both sides by -3:
simplify: x=2
Y-intercept is (0,2) bc that’s where the line hits the y-axis.(the up and down line)
The slope is 1/2 because you go up one over two coordinate to get to the next dot.
The equation is y=Mx+b
M is the slope
X is the amount of times you use the slope
B is the initial value
Y=1/2x+2
Answer:
Roots are complex numbers
Step-by-step explanation:
we know that
In a quadratic equation of the form 
The discriminant is equal to 
If
-----> The equation has only one real root
If
-----> The equation has two real roots
If
-----> The equation has complex roots
In this problem the discriminant is -8
so
-8 < 0
therefore
Roots are complex numbers
