Find the slope of the line (-3,-2) (1,6)

nlexa [21]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (1, 6)

m = $\frac{6-(-2)}{1-(-3)}$ = $\frac{6+2}{1+3}$ = $\frac{8}{4}$ = 2

Answer:

A y = 3x

Step-by-step explanation:

We can check each line to see if the point is on it

A y = 3x 6 = 2*3 6=6 this is true so the point is one the line

B y = 4-x 6 = 2-4 6 = -2 false

LABC measures 90° and ZABD measures<br> 25. What is the measurement of ZDBC?

makkiz [27]

Answer: The measurement of angle DBC is 65 degrees

Step-by-step explanation:

Line BD splits ABC into two angles ABD and DBC.

If ABC is 90 then the measures of ABD + DBC will be 90. Since we know the measure of ABD we can make this equation and solve it

$90=25+x\\90-25=25+x-25\\65=x$
