Answer:
3). y = 2x - 2
4). y = (4/3)x - 1
Step-by-step explanation:
3).
First find the slope
(y2 - y1) / (x2 - x1) or rise/run
(0 - (-2)) / (1 - 0) = 2
2 is your slope
Now use the equation below for using coordinates for finding slope intercept form.
y - y1 = m(x - x1)
y1 = y number of given coordinate
x1 = x number of given coordinate
m = slope
y - 0 = 2(x - 1)
Distribute
y - 0 = 2x + (-2)
Get y by itself by adding 0 to both sides.
y - 0 = 2x + (-2)
+0 +0
y = 2x - 2
4).
Repeat the same process for 4 as done in 3
Find the slope
(y2 - y1) / (x2 - x1) or rise/run
(3 - (-1)) / (3 - 0) = 4/3
4/3 is your slope
Now use the equation below for using coordinates for finding slope intercept form.
y - y1 = m(x - x1)
y1 = y number of given coordinate
x1 = x number of given coordinate
m = slope
y - 3 = (4/3)(x - 3)
Distribute
y - 3 = (4/3)x + (-4)
Get y by itself by adding 3 to both sides.
y - 3 = (4/3)x + (-4)
+3 +3
y = (4/3)x - 1
