Question

What is the slope-intercept equation for the line below?

Answer 1

Answer:

y = 2/5x+2

Step-by-step explanation:

First find the slope

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

    = (4-2)/(5-0)

    =2/5

The y intercept is 2

The slope intercept form is y = mx+b

where m is the slope and b is the y intercept

y = 2/5x+2

Answer 2

Answer:

y = mx + c

1) find the gradient, m

$m = \frac{4 - 2}{5 - 0}$

$m = \frac{2}{5}$

2) find value of y-intercept, c

from the graph, c = 2

2) use the formula y=mx+c

y = mx + c

y = 2/5x + 2

the answer is A
