What is an equation of a line,in point-slope from, that passes through (1, -7) and has a slope of -2/3
il63 [147K]

Answer:

y + 7 = - \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

Where m is the slope and (a, b) a point on the line

Here m = - \frac{2}{3} and (a, b) = (1, - 7), thus

y - (- 7) = - \frac{2}{3}(x - 1), that is

y + 7 = - \frac{2}{3}(x - 1) ← in point- slope form

If c is a positive integer, how does the graph of y=x+c compare to the graph of y=x?
Len [333]

Answer:

It is shifted c units to the left  .

Step-by-step explanation:

In general, adding a constant c to the value of x shifts a graph c units to the left.

The graph of y = x + c is parallel to y = x,  the y-intercept becomes (0, c) and the x-intercept becomes (-c, 0).

In the diagram below, the red line is the graph of y = x, and the blue line is the graph of y = x + 1.

PLEASE HELP!!!<br> Find MG.<br> ∆EGF~∆EML.
stiv31 [10]

Answer:

MG=56\ units

Step-by-step explanation:

step 1

Find the value of x

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem we have that

∆EGF~∆EML

so

\frac{EG}{EM}=\frac{EF}{EL}

substitute the given values

\frac{5x+2}{16}=\frac{126}{28}

solve for x

5x+2=\frac{126}{28}(16)

5x+2=72\\5x=70\\x=14

EG=5x+2=5(14)+2=72\ units

step 2

Find MG

we know that

MG=EG-EM

substitute

MG=72-16=56\ units
