4x - 3y = -2
3y = 4x + 2
y = 4/3 x + 2/3
Answer: y = 4/3 x + 2/3
Answer:
d
Step-by-step explanation:
because I said
Answer:
Base at the top should be the same length, thus 20ft.
right triangle thus 90 degrees angle.
180 - 90 - 40 = 50
20ft/sin50 = Height/sin40
Height of the traffic light = 16.78
16.78 + the height of Andrew eyes ( 5ft) = 21.78
Answer:
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0).
First, we must find the slope (<em>m</em>).
where two points that fall on the line are and
Two points that are highlighted for us on the graph are (-3,-2) and (5,4). Plug these into the equation:
Therefore, the slope of the line is 3/4. Plug this into :
Now, to find the y-intercept (<em>b</em>), our first resort would be to find it on the graph. However, on the graph, it appears ambiguous. So, we must solve it algebraically.
Plug in the point (5,4) and solve for <em>b</em>:
Therefore, the y-intercept is . Plug this back into :
I hope this helps!
