Write an equation in slope- intercept form y=mx=b of the line through point p(6,7) with slope -2

The equation would be y = -2x + 19

Step-by-step explanation:

To find this, we can use the point and the slope in point-slope form. The we solve for y.

y - y1 = m(x - x1)

y - 7 = -2(x - 6)

y - 7 = -2x + 12

y = -2x + 19

207/8 is the right

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
