Write the equation of the line fully simplified slope-intercept form.

zmey [24]

Answer:5y=x-35

Step-by-step explanation:

The given line passes through the points $(0,-7)$ , $(10,-5)$ .

Let the slope of the line be $m$ .

If a line passes through $(x_{1},y_{1})$ and $(x_{2},y_{2})$ ,then

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

So, $m=\frac{-7-(-5)}{0-10}=\frac{1}{5}$

Y-intercept of a line is defined as the y-coordinate of the point where the line touches y axis.

Let the y intercept be $b$

From the graph, $b=-7$

The equation of the line with slope $m$ and y-intercept $b$ is $y=mx+b$

So, $y=\frac{1}{5}x-7$

$5y=x-35$

HELP: Will Award Brainliest! Simplify 17x - 12 = 114 + 3x

mrs_skeptik [129]

Answer:

x=9

Step-by-step explanation:

17x - 12 = 114 + 3x

First Subtract 3x from both sides

14x - 12 = 114

Add 12 to both sides

14x=126

Divide by GCF (14)

x=9

The triangles below are similar; find the correct value of x. If necessary, round to the nearest tenths place.
