y = mx + b is the basic equation for a straight line

.

m is a negative number when the straight line falls

b, c and f fall

.

for the slope you think of a climbing triangle.

Where to put it, is not fixed

At the beginning and end, however, grid points should be where the lines intersect

.

6 down

4 to the left

m = – 6/4 = – 3/2

b is + 1

y = -3/2 x + 1

.

How much up / right?

m = + top/right

The Ersre is credible y=-0.5/1×2 but net sure just read nenner and counter and see if it goes down

If it is a straight line, then potencies of x, like x2 are not necessarily the best starting point …

The task is to specify the following items for each of the images:
(a) The slope – so how much the line goes up or down – (you always look in the reading direction from left to right)

b) the y-axis section – i.e. at which y-value intersects the y-axis

c) the assignment rule, i.e. the equation which describes this function. This is almost done by the first two parts of the task. In general, the assignment rule of a straight line y=mx+b. m is the slope and b of the y-axis section.
