Answer:

x=2

Step-by-step explanation:

If this figure is a rhombus, then the two sides have to be equal:

3x+9=8x-1

Move like terms to one side (note that when you move it, the sign flips. Ex: - becomes +)

3x-8x=-9-1

-5x=-10

Divide both sides by -5

x=2

A line has a slope of 1 and passes through the point (7,5). What is its equation in

GrogVix [38]

Answer:

$y=x-2$

Step-by-step explanation:

Slope-intercept form is $y=mx+b$ , so if $m=1$ , then we have $y=x+b$ and we'll need to plug in $(7,5)$ to get $b$ , the y-intercept:

$y=x+b$

$5=7+b$

$-2=b$

Therefore, the final equation in slope-intercept form is $y=x-2$
