-4/7 + 2/7x - 14x + 4/7

alexgriva [62]

Answer:

The solved given expression is

$\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}$

Step-by-step explanation:

Given expression is $\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}$

To solve the given expression :

$\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}$

$=\frac{-4+4+2x}{7}-14x$

$=\frac{0+2x}{7}-14x$

$=\frac{2x}{7}-14x$

$=\frac{2x-14x(7)}{7}$

$=\frac{2x-98x}{7}$

$=\frac{-96x}{7}$

Therefore $\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}$

Therefore the solved given expression is

$\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}$

Graph a line that passes through (1,3) and has a slope of 2

castortr0y [4]

Answer: y=2x+1

Step-by-step explanation:

Let's use point-slope form which is y-y1 = m(x-x1)

Let's substitute these in.

y-3 = 2(x-1)

y-3 = 2x-2

y = 2x+1

When graphed on desmos it looks like this:
