y=-7x+2

m=-7, so that's a negative slope.

b=2, so the y-intercept is (0,2). That's a postiive y-intercept.

Solve 0=-7x+2 to find the x-intercept.

7x=2

x=2/7

The x-intercept is (2/7,0), so that's a positive x-intercept.

Solve the following system. y = x 2 - 9x + 10 and x + y + 5 = 0. Enter the solution with the smaller x value first.

X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)

1. Determine whether line KM and line ST are Parallel, Pers

Andrews [41]

Answer:

Since the slope of KM and ST are different, they are not parallel

Step-by-step explanation:

Slope of line KM = $\frac{5}{8}$

Slope of ST = $-\frac{8}{5}$

Determine whether the lines are perpendicular;

Solution:

We can use the slope of a line to determine whether they are perpendicular or parallel to one another.

Parallel lines do not meet one another

Perpendicular lines cross one another at an angle of 90°

Two lines are parallel if their slopes are the same;

Since the slope of KM and ST are different, they are not parallel
