Answer:
By putting the coordinates on the graph I think
Step-by-step explanation:
2x - 1 + 3x + 6 = 90°
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85/5
x = 17°
ANSWER:
y intercept = (0,-6/5)
x intercept = (-3,0)
EXPLANATION:
To find the y intercept you have to substitute the x with zero because the y intercept always lies on the y axis which means that they will always have the coordinates (0,y)
The same goes for the x intercept. To find the x intercept you have to substitute the y with zero because the x intercept always lies on the x axis which means that they will always have the coordinates (x,0)
WORKING OUT:
Given=2x+5x= -6
The y intercept)
x=0
2(0)+5y= -6
5y= -6
y = -6/5 (divide each side of the equation by t to get the y alone)
y intercept = (0,-6/5)
The x intercept)
y=0
2x+5(0)= -6
2x= -6
x = -3 (divide each side of the equation by t to get the x alone)
x intercept = (-3,0)
First find the slope between any two points:

Where

are the two points
So calculating the slope:

So the slope is

And our equation will be in the format of

where

and

So, now we have half of the equation:

Now to calculate b, we can plug in a point

and solve for b.
So

Lets use the point

So:

And then:

So our final equation is
