Write an equation for the line in slope-intercept form.
2 answers:
y - 3x - 3
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (- 2, 3 ) ← 2 points on the line
m = =
= - 3
The y-intercept = (0, - 3 ) ⇒ c = - 3
y = - 3x - 3 ← in slope-intercept form

Here, ∠1 and ∠2 are complementary angles which means they together are forming a right angle or we can also say that their sum is 90°.So, According to this:
- ∠1 = x-8
- ∠2 = 6x
<em>Thus, The measure of m∠1 is 6° and measure of m∠2 is 84°...~</em>
