Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
Then, plug these coordinates into the <em>Slope-Intercept Formula</em> instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:
35 = 4[3] + b
12
Then convert to <em>Standard</em><em> </em><em>Form</em>:
y = 4x + 23
- 4x - 4x
__________
_______________________________________________
19 = 4[−1] + b
−4
Then convert to <em>Standard Form</em>:
y = 4x + 23
- 4x - 4x
__________
** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.
