4. Use the slope and the y-intercept to graph the following equation. 3y + 6 = -2x
1 answer:
Answer:
slope = - 2/3,y = -2
Step-by-step explanation:
- Make y the subject of the line 3y + 6 = -2x.
- Divide throughout by three to get the slope.
- Get the y - intercept by substituting x = 0.
- The slope gotten is -2/3.
- The y - intercept is y = - 2.
- in plotting the graph, make a point at - 2 on the y - axis which is the y - intercept. Then count three steps from the origin on the x - axis towards the negative direction and mark a point on - three.

Answer:
The measure of arc EF = 41°
Step-by-step explanation:
Given:
Arc DE = 73°
Now, we know from central angle theorem that the measure of central angle by an arc is twice that of the angle made by the same arc at the circumference. Therefore,
Now, we know that sum of all arcs on a circle is equal to 360°.
Therefore, arc DGF + arc DE + arc EF = 360°
Therefore, the measure of the arc EF is 41°.
