Answer:
Step-by-step explanation:
To find the x-intercept, set y=0 and solve for x. That will mean dividing by the coefficient of x:
-4x +0 = -16
x = -16/-4 = 4 . . . . the x-intercept
__
To find the y-intercept, set x=0 and solve for y. That will mean dividing by the coefficient of y:
0 +8y = -16
y = -16/8 = -2 . . . . the y-intercept
__
The x- and y-intercepts are (4, 0) and (0, -2), respectively.

<em>Additional comment</em>
The standard form equation of a line, ax+by=c, is especially nice for finding the intercepts, as they are always (c/a, 0) and (0, c/b). Once you see this, you can do a question like this in your head.
Answer:
(0,3) and (1,4) are solution sets of given system
Step-by-step explanation:
Given that:
y= 3x^2−2x+3 ------------- eqA
y = x + 3 ------------------ eqB
Putting value of y from eqB to eqA
x + 3 = 3x^2−2x+3
Taking all variables to left side:
Signs pf transferred terms will be changed
3x^2−2x+3 - x - 3 = 0
Adding like terms we get:
3x^2−3x = 0
Dividing both sides by 3 we get:
x^2 - x = 0
Now take x common:
x(x-1)= 0
So
x = 0 and x = 1
Now put value in eqB
y = 0 + 3 and y= 1 + 3
we get:
y = 3 and y = 4
So solution sets are:
(0,3) and (1,4)
