Answer:

2x + y = 3 => y = 3-2x

then

4x+4(3-2x) = 8

4x+12-8x= 8

-4x = -4

x=1

y=3-2*1 = 1

A line intersects the point (3,-4)and has a slope of 17 .what is the slope - intercept equation for this line?
vladimir1956 [14]

Answer:

The slope - intercept equation for this line is y = 17x - 55

Step-by-step explanation:

The general form of the slope-intercept form is

y = mx +b

where m is the slope and b is the y-intercept.

We are given slope m = 17

we need to find b the y-intercept.

To find y-intercept we would use point(3,-4) and formula

y = -4

x = 3

m = 17

b=?

y = mx + b

-4 = (17)(3) + b

-4 = 51 + b

b = -4 -51

b = -55

So, y-intercept is -55

The slope - intercept equation for this line is y = 17x - 55
