Find the slope x intercept and y intercept of the line y equals 2x + 1

Ad libitum [116K]

(i) Slope is $m=2$

(ii) x - intercept is $\left(-\frac{1}{2}, 0\right)$

(ii) y - intercept is $(0,1)$

Explanation:

The given equation is $y=2x+1$

We need to determine the slope, x - intercept and the y - intercept

(i) Let us determine the slope of the equation.

Since, the equation is of the form $y=mx+b$ where m is the slope

Thus, comparing the equation $y=2x+1$ with the general form $y=mx+b$ , the slope is 2.

Thus, slope is $m=2$

(ii) Now, we shall determine the x - intercepts.

The x - intercept can be determined by substituting $y=0$ in $y=2x+1$

Thus, we have,

$0=2x+1$

$-1=2x$

$\frac{-1}{2} =x$

Thus, the x - intercept is $\left(-\frac{1}{2}, 0\right)$

(iii) The y - intercept can be determined by substituting $x=0$ in $y=2x+1$

Thus, we get,

$y=2(0)+1$

$y=0+1$

$y=1$

Thus, the y - intercept is $(0,1)$

Helping my 2nd grader with his math homework and came across this. I don't know Common Core but I can find the sum "the old fash

n200080 [17]

427+316

step one- add 400 and 300=700
step two- take 3 from the 16 and add it to the 27 and add - 27+3+13=43
step three- add 43 and 700

I think that the common core way just adds more steps and makes it more complicated than just adding it regularly, but that's just me.

In the equation, t is a constant. If the equation has no real solutions, what could be the value of t? 2x^2 − 4x = t please help

swat32

2x^2-4x=t

2x(x-2)=t

if t=0:

0=2x(x-2)

$\frac{0}{2(x - 2)} = x$
