Question

find the equation of a line that satisfies the given conditions; x-intercept 2, and y-intercept -8

Answer 1

so the points are (2,0) and (0,-8) use the definition of slope which is \[m = \frac{y2 - y1}{x2 - x1}\] to find the slope and then use the point slope formula \[y - y1 = m(x - x1)\]

Answer 2

To write the equation

Answer 3

So what do you get for the slope?

Answer 4

slope is 4

Answer 5

yeah the slope is 4

Answer 6

Good.. so m = 4 and we can choose anyone of those points above to write the equation.. So pick what point you want to use.

Answer 7

y+8=4x
