Answer 1

pick 2 points on your graph...(-2,4) and (0,1)
we are gonna find the slope by using the slope formula :
slope(m) = (y2 - y1) / (x2 - x1)
(-2,4)...x1 = -2 and y1 = 4
(0,1)...x2 = 0 and y2 = 1
now we sub
slope(m) = (1 - 4) / (0 - (-2)
slope(m) = -3/2

y = mx + b
using points (-2,4)...x = -2 and y = 4
slope(m) = -3/2
now we sub
4 = -3/2(-2) + b
4 = 3 + b
4 - 3 = b
1 = b

equation is : y = -3/2x + 1 <== answer is slope intercept form
and if you need it in standard form Ax + By = C
y = -3/2x + 1 --multiply by 2
2y = -3x + 2 -- add 3x to both sides
3x + 2y = 2 <== answer in standard form

Thank you soooo much for your help
