Question

Write the equation of the line given by the following graph in slope-intercept form.
y = –2x + 86
y = –2x – 10
y = –2x – 8
y = –2x + 10

Answer 1

Here, slope intercept form is y = mx + b. The "b" part is the y-intercept (where the line crosses the y-axis). Here you can see the y-intercept is clearly negative. That eliminates 2 equations. To find the x-intercept, set y = 0 and solve for x.

Answer 2

i'm a visual learner.. can you explain a little moree, please ?

Answer 3

The y-axis is the vertical one. Here you can see that the line crosses it below 0, right?
