Answer:

Step-by-step explanation:

The equation of a line is y=mx+b where m is slope and b is the y-intercept. the y-intercept is where the line crosses the y-axis which is at (0,2) here so b=2.

The slope is found by finding the difference between any two points on the line. To find the difference, choose two points which cross through two grid lines. The only points on this graph which does that is (0,2) and (10,15). Find the slope by subtracting 15-2 / 10-0. This is equal to 13/10 or 13 over 10.

The equation is y = 13/10 x +2.

A line passes through (3, -2) and (6,2). Write an equation for the line in point-slope form.

snow_lady [41]

Answer:

4x - 3y -18 = 0 or y = 4x/3 - 6

Step-by-step explanation:

We will have to find the slope of the line first

The formula for slope:

$m =\frac{y_{2}- y_{1} }{x_{2} -x_{1} } \\m= \frac{-2-2}{3-6}\\ =\frac{-4}{-3}\\ =\frac{4}{3}$

The standard form of equation of a line is:

y = mx + b

We know m,

So the equation will be:

$y= \frac{4}{3}x+b$

We have to find the value of b, for that we will put any one of the point in the equation

So, putting (6,2)

2 = 4/3 * 6 + b

2 = 8 +b

b = -6

Putting the value of m and b in the standard form of equation of line,

$y = mx + b\\y = \frac{4}{3}x+(-6)\\y = \frac{4}{3} x - 6\\Multiplying\ both\ sides\ by\ 3\\3y = 4x - 18\\4x - 3y -18 = 0$ ..
