Answer:
Step-by-step explanation:
<u>Given information</u>:
- Slope = 4
- Point on line = (-1, 2)
<u>Point-slope form</u><u> of linear equation</u>:
(where m is the slope and (x₁, y₁) is a point on the line)
Substitute the given slope and point into the formula:
<u>Slope-intercept form</u><u> of a linear equation</u>:
(where m is the slope and b is the y-intercept)
Substitute the given slope and point into the formula and solve for b:
Therefore:
<u>Standard form</u><u> of a linear equation</u>:
(where A, B and C are constants and A must be positive)
Rearrange the found slope-intercept form of the equation into standard form:
