Answer:

im kind of rusty on this math but i think the equation would be y=-5x+b  i forgot how to find b tho :( im sorry

A line passes through the point (-4,-5) and had a slope of 5/2. Write an equation in slope-intercept form
daser333 [38]

Step-by-step explanation:

as we have a point and the slope, we can start with the point-slope form and then transform.

the point-slope form is

y - y1 = a(x - x1)

(x1, y1) being a point on the line, a being the slope.

the slope-interceot form is

y = ax + b

a being the slope again, b being the y-intercept (the y value for x = 0).

so, we have

y - -5 = 5/2 × (x - -4)

y + 5 = 5/2 × (x + 4) = 5x/2 + 5×4/2 = 5x/2 + 10

y = 5x/2 + 5

or

y = (5/2)x + 5

and this is already the slope-intercept form. all done.

Can someone please help me on e and f i dont understand it and pls explain
Lemur [1.5K]
For parts A, B, C, and D you most likely created a line. What question E is asking is for you to create a line that is perpendicular to the line you already created that also passes through the point (1,1). What is important to understand here is that the slope of the perpendicular line is the negative reciprocal of the original line's slope... if the original slope is (-4/3) than the perpendicular slope is (3/4)... then you should just plug that new slope into point-slope form or slope-intercept form to get your equation... y-y1 = m(x-x1) ... y-1= (3/4)(x-1) ... so it would be y=(3/4)x + 1/4 then for part f just convert into standard form which is just manipulating the variables... look up standard form equation on Google and manipulate the variables from there.

Determine if the lines -2x + 3y = -1 and 6x + 4y = 4 are parallel, perpendicular or neither. Explain.
xz_007 [3.2K]

Answer:

Perpendicular

Step-by-step explanation:

-2x+3y=-1

6x+4y=4

----------------

3y=-1-(-2x)

3y=-1+2x

3y=2x-1

y=2/3x-1/3

-----------------

4y=4-6x

4y=-6x+4

y=-6/4x+4/4

y=-3/2x+1

--------------------

2/3 and -3/2 are negative reciprocals, therefore, they are perpendicular.
