Find the slope-intercept form of an equation for the line that passes through (–1, 2) and is parallel to y = 2x – 3.

sammy [17]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut point with the y axis.

By definition, if two straight lines are parallel then their slopes are equal. Thus, the slope of the line sought will be $m = 2.$

$y = 2x + b$

We substitute the given point to find b:

$2 = 2 (-1) + b\\2 = -2 + b\\2 + 2 = b\\b = 4$

Finally the line is:

$y = 2x + 4$

Answer:

$y = 2x + 4$

The ratio of the measures of the three angles in a tangle 3107. Find the measures of the angles and write them in size order,

N76 [4]

Answer:

27, 90 and 63

Step-by-step explanation:

Given

Ratio of triangle sides

$Ratio = 3 : 10 : 7$

Required:

The length of each side

Triangles in a triangle add up to 180.

The side with ratio 3 is:

$S_1 = \frac{3}{3 + 10 + 7} *180$

$S_1 = \frac{3 *180}{20}$

$S_1 = \frac{540}{20}$

$S_1 = 27$

The side with ratio 10 is:

$S_2 = \frac{10}{3 + 10 + 7} *180$

$S_2 = \frac{10 *180}{20}$

$S_2 = \frac{1800}{20}$

$S_2 = 90$

Lastly:

The side with 7 as its ratio

$S_3 = \frac{7}{3 + 10 + 7} *180$

$S_3 = \frac{7 *180}{20}$

$S_3 = \frac{1260}{20}$

$S_3 = 63$

Hence, the angles are: 27, 90 and 63
