Identify the x and y intercepts for the following equation, then convert to slope intercept form. -5x – y= -15

X intercept: (___,0)
Y intercept: (0,___)

Slope intercept form y=___x+___

Please help me fill in the blanks :(

(3;0)

(0;15)

y=-5x+15

Step-by-step explanation:

x-intercept

-5x–0=-15

-5x=-15

-5x/-5=-15/-5

x=3 》》(3;0)

y-intercept

-5(0)-y=-15

y=15 》》 (0;15)

slope intercept form

y=mx+b

m=Y2–Y1/X2–X1

=15–0/0–3

=15/-3

=-5

evalute (0;15) & m=-5 in y=mx+b

15=-5(0)+b

15=b

so

y=-5x+15

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
