2. Write the slope-intercept form of the equation for each graph described. Line passing through (-5, 12) and parallel to the li
Nostrana [21]

Answer:   y = 2x+22

========================================================

Explanation:

The equation y = 2x+5 is in the form y = mx+b

m = 2 = slope

b = 5 = y intercept

Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.

Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c

y = mx+c

12 = 2(-5)+c

12 = -10+c

12+10 = c

22 = c

c = 22

Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22

The equation of the parallel line is y = 2x+22

The graph is below.

Answer:

<h2>6 \frac{3}{10}</h2>

Step-by-step explanation:

4 \frac{1}{5}  \div  \frac{2}{3}  =  \frac{21}{5}  \div  \frac{2}{3}  =  \frac{21}{5}  \times  \frac{3}{2 }  \\  \\  =  \frac{63}{10}  = 6 \frac{3}{10}

If the measure of arc DEF is 248°, what is the measure of ∡DEF?
HACTEHA [7]
The figure attached has <DEF which is an inscribed angle. An inscribed angle is an angle with its vertex on the circle which is formed by two intersecting chords. According to formulas, the measurement of arc DF is twice the measurement of ∡DEF. Arc DF is equal to 360-248 or 112. Hence <span>∡DEF is equal to 56 degrees.</span>
