Answer:

2x+9=12x-21

-2.      -2

9=10x -21

+21           +21

30=10x

Divide by 10 on both sides

30/10

x=3

Write an equation in point-slope form for the line.<br> (1,3) <br> (0,1)<br> m=4
Anna [14]

Given coordinates (1,3) and (0,1).

In order to find the equation of line, we need to find the slope between given coordinates.

We know slope formula,

m= \frac{y2-y1}{x2-x1}

We have (x1,y1) = (1,3) and (x2,y2) = (0,1).

Plugging values of x1,y1,x2 and y2 in slope formula, we get

m=\frac{1-3}{0-1}

Simplifying top and bottom of the fraction we got for slope

m=\frac{-2}{-1}=2

We got slope m=2.

We are given second point (0,1), where x-coordinate is 0 and y-coordinate is 1.

y-intercept is a point on y-axis, where x=0.

Therefore, y-intercept = 1.

Now, applying slope-intercept form of the linear equation

y=mx+b, where m is the slope and b is y-intercept.

m=2 and b=1.

Plugging values of m and b in slope-intercept form, we get

y=2x+1.

Therefore, point-slope form for the line is y=2x+1.
