Equations of Lines in Different Forms

1. Which equation from the three scenarios is in slope-intercept form?
Answer:
The slope-intercept form of an equation of line is: y = mx + b.
Comparing the three equations given with the standard slope-intercept form,
the equation
y = 1.8x + 4
is the correct choice.
Identify each of the following from the equation: m = b =
We have,
y = mx + b ' y = 1.8x + 4
Therefore,
m = 1.8 b = 4
2. Which equation from the three scenarios is in point-slope form?
Answer:
The point-slope form of an equation of line is: y − y1 = m(x − x1).
Comparing the three equations given with the standard point-slope form,
the equation
y − 96 = 18(x − 5)
