Hey there! :)

Let's put all of our facts down first. We know that slope-intercept form is y=mx+b , where m=slope & b is the y-intercept.

So, if we're given the slope and y-intercept, then we can very simply plug those values into slope-intercept form!

Our slope is 4 and our points are (0, -1).

y = mx + by = (4)x + (-1)

Get rid of our parenthesis.y = 4x - 1

So, our equation of the line that passes through (0, -1) and has a slope of 4 is y = 4x - 1

~Hope I helped!~

Which ordered pair is the best estimate for the solution of the system of equations?
Brums [2.3K]

For this case we have the following system of equations:

y = - \frac {3} {4} x-2\\y = x + 6

Equaling the equations we have:

- \frac {3} {4} x-2 = x + 6\\-2-6 = (1+ \frac {3} {4}) x\\-8 = \frac {7} {4} x\\-32 = 7x\\x = \frac {-32} {7}\\x = -4.57

The variable y:

y = -4.57 + 6 = 1.43

Thus, we can round the solution as:

(x, y): (- 4.5; 1.5)

It is verified with the graph

If triangle abc is similar to triangle mno how do I solve for value of missing side
Doss [256]

Answer:

=2.4 cm

Step-by-step explanation:

In similar plane figures, the ratio of corresponding sides is a constant.

This constant is the linear scale factor.

In the provided example, 1.2cm corresponds to 0.96 while 3.0 corresponds to x

Thus, 1.2 cm/0.96 cm=3.0 cm/x

x=(3.0 cm×0.96 cm)/1.2 cm

=2.4 cm.

QR has endpoints at Q (11, 13) and R(7, 14). Find the midpoint M of QR
cricket20 [7]

Answer:

M=(9, 13.5)

Step-by-step explanation:

What you do is you need to use the midpoint formula.

(x_1+x_2/2), (y_1+y_2/2).

(11, 13) and (7, 14) are your points and you put those numbers into the equation.

11 and 7 are x and 13 and 14 are y.

(11+7/2), (13+14/2)

M=(9, 13.5) is your answer.
