Question

Writing Equations of lines

Answer 1

Answer:

y = -5/3x+8

Step-by-step explanation:

Equation: y=mx+b

You find the slope (m) by calculating the distance between the two points. For the y axis, 3 is -5 away from 8. For the x axis, 3 is 3 away from 0. You then devide y by x, which gives you -5/3.

To get the y intercept (b), you just look at the graph, where it's at 8.

God luck!

Answer 2

Answer:

y = -5/3x + 8

Step-by-step explanation:

Points on the graph: (0, 8) and (3, 3)

Slope:

m=(y2-y1)/(x2-x1)

m=(3-8)/(3-0)

m= (-5)/3

m= -5/3

Slope-intercept:

y - y1 = m(x - x1)

y - 8 = -5/3(x - 0)

y - 8 = -5/3x

y = -5/3x + 8
