Answer:
y = x + 15
Step-by-step explanation:
okay so you're gonna use the y2-y1/x2-x1 formula to find the slope (m)
24 - 19/9 - 4 = 5/5 = 1
so that is your slope (m)
and now if you follow your slope then you should get your y-intercept (b)
4 - 1 = 3 19 - 1 = 18
(3, 18)
3 - 1 = 2 18 - 1 = 17
(2, 17)
2 - 1 = 1 17 - 1 = 16
(1, 16)
1 - 1 = 0 16 - 1 = 15
(0, 15)
so thats your y-intercept (b)
and the equation will look like:
y = mx + b y = x + 15 or y = 1x + 15 (but the 1 isn't necessary)

It's 6. AND BRAINLY STOP DELETING MY POST IT'S RELATED TO SCHOOL!!
Step-by-step explanation: 6
Answer:
y = 3 - 4x
To find the y intercept let x = 0
y = 3 - 4(0)
y = 3 or ( 0 ,3)
Hope this helps.
Answer:
The equation of the line joining the points (-1,-1), (1,-1) is
y +1 =0
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given curve y = 2 x² -3 , x = -1 and x=1
substitute x =-1 in given curve y = 2 x² -3
y = 2 (-1 )² - 3
y = 2 -3
y = - 1
First point A( -1 ,-1)
substitute x =1 in given curve y = 2 x² -3
y = 2 (1)² - 3
y = -1
Second point B( 1 , -1 )
<u><em>Step(ii):-</em></u>
A( -1, -1 ) and B( 1,-1)
slope of the line
The equation of the straight line passing through the point ( -1,-1 ) having slope m =0
y - y₁ = m ( x - x₁ )
y - (-1) = 0( x-(-1)
y +1 =0
The equation of the line joining the points (-1,-1), (1,-1) is y +1 =0
Step-by-step explanation:
Take the number as x
12x-40=7x+25
collect like terms
12x-7x=25+40
5x=65(divide both sides by 5)
x=13
Therefore number is 13
