Question

Please help? I'm so confused. :\
"Write an equation in slope-intercept, point-slope, or standard form for the line with the given information. Explain why you chose the form you used.
a) passes through (-1, 4) and (-5, 2)

b) slope 2, y-intercept -4

c) has an x-intercept of 6 and a y-intercept of 3

d) passes through (1, 2) with slope -5/3

Answer 1

You need to start with definitions of what are slope-intercept, point-slope, and standard forms, right @Breezehh ???

Answer 2

Yeah..

Answer 3

a ) slope point form
y - y1 = m(x - x1)
where m = (y2 - y1)/(x2 - x1)

b ) slope intercept
y = mx + c

c) intercept form
a is x intercept and b is y
x/a + y/b = 1


d)slope point form
y - y1 = m(x - x1)

Answer 4

got it

Answer 5

thank you. I don't understand it but I have to turn something in lol

Answer 6

Askaway :)

Answer 7

If you want to learn something, you have to put in the effort of learning.

Answer 8

$$\Huge \text{a) passes through (-1, 4) and (-5, 2)}$$

$$\Huge \text {let }{ x_1=-1 \text{ and } y_1=4}$$
$$\Huge \text {let }{ x_2=-5 \text{ and } y_2=2}$$

$$\Huge \text{slope point form}$$
$$\Huge y - y_1 = m(x - x_1)$$
$$\Huge{where}$$
$$\Huge m = \frac{(y_2 - y_1)}{(x_2 - x_1)} $$
