Answer:
An equation that makes a straight line when it is graphed. Often written in the form y = mx+b. Equation of a Straight Line
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
The slope can be found from two points.
The two points from the graph are (1, 9) and (2, 12).
Plugging in the values and evaluating.
The slope of the line is 3.
The y-intercept of the line is where the line cross the y-axis.
The line crosses the y-axis at (0, 6).
The slope-intercept form of the line is:
Complementary angles ⇒ the angles add up to 90°
∠A and ∠B are complementary ⇒ ∠A + ∠B = 90°
∠A + ∠B = 90°
Plug in the values for ∠A and ∠B:
(3x - 8) + (5x + 10) = 90
Open the brackets:
3x - 8 + 5x + 10 = 90
Combine like terms:
8x + 2 = 90
Subtract 2 from both sides:
8x = 88
Divide both sides by 8:
x = 11
Answer: x = 11
An undefined slope is just a vertical line so g would equal -7
Rational im pretty sure from what i remember
