1 rational solution

4x² + 12x + 9 = 0
(2x+3)²=0
2x + 3 =0
2x +3 -3 = 0-3
2x = -3
2x/x = -3/2
x = -3/2

? is the y-intercept.

Looking at the line that we have graphed, we can see that it intersects at  34/7 y.

the equation for the line that goes through 4,6 and -10, 2 is

How to find the point-slope form for the slope of 6 and passing through(-7,1)​
MariettaO [177]

Answer: y-1=6(x+7)

Step-by-step explanation:

The formula for point-slope form is y-y_1=m(x-x_1). Since we are given the point and slope, we can directly plug them in.

y-1=6(x-(-7))            [distribute by -1]

y-1=6(x+7)

Now, we know that the point-slope form is y-1=6(x+7).
