Write an equation of the line with a slope of 3/4 and y-intercept of -2

aleksandr82 [10.1K]

The slope intercept form equation is this
y = mx + b
m being the slope and b being the y intercept
So, an equation of a line with a slope of 3/4 and a y-intercept of -2 would look like this
y = 3/4x - 2
I hope this helps.
YOU'RE WELCOME :D

What are the possible values of x in 8x2 + 4x = -1?

Westkost [7]

Answer:

The possible values of x are:

x= $\frac{-1+\sqrt{3}}{4} \,\,or\,\, x= 0.18$

and

x= $\frac{-1-\sqrt{3}}{4} \,\, or \,\, x= -0.68$

Step-by-step explanation:

$8x^2+4x+1=0$

Using Quadratic formula to solve this equation:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\a = 8 \,\, b = 4\,\, c = -1\\Putting \,\, values \,\, in \,\, the\,\, equation\\x= \frac{-4\pm\sqrt{(4)^2-4(8)(-1)}}{2(8)}\\x= \frac{-4\pm\sqrt{16+32}}{16}\\x= \frac{-4\pm\sqrt{48}}{16}\\x= \frac{-4+ \sqrt{48}}{16} \,\, and \,\, x= \frac{-4- \sqrt{48}}{16}\\x= \frac{-1+ \sqrt{3}}{4} \,\, and \,\, x= \frac{-1- \sqrt{3}}{4}$

The possible values of x are:

x= $\frac{-1+\sqrt{3}}{4} \,\,or\,\, x= 0.18$

and

x= $\frac{-1-\sqrt{3}}{4} \,\, or \,\, x= -0.68$

Drag equations to each row to show why the equation of a straight line is y = 2x + 5, where 2 is the slope and 5 is the y-interc

Vedmedyk [2.9K]

Answer: y-5/x =2/1 for the two triangles on the graph are similar

Y-5=2x for multiple both sides by x

Y=2x+5 for add 5 to both sides
