5 0

Answer:

3rd option

Step-by-step explanation:

The dotted line at x=3 removes the 2nd one

Cus it's a dotted line, the > sign has no line under it so not 1st option

last option has y intercept at 1 but the graph's y intercept is at -2 so it's not it

If line b is perpendicular to line a, and line c is

Nikolay [14]

Answer:

y=x-2.5

Step-by-step explanation:

If it is perpendicular to a, just like b, it has the same slope, but, it has a y-intercept of 2.5, unlike b, which has a y-intercept of 1

Answer:

x = 64 degree , 2x = 128 degree

Step-by-step explanation:

2x = 128 (being alternate interior angles)

x = 128/2

x = 64 degree

=2*64

=128 degree

What is the slope of the line that passes through the points (4, 7) and (8, 9)

SSSSS [86.1K]

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = $\frac{y{2}-y{1} }{x{2}- x{1} }$ = $\frac{y}{x}$

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = $\frac{8-4}{9-7}$

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = $\frac{8-4}{9-7}$ = $\frac{2}{4}$

Simplify,

⇒ $\frac{2}{4}=\frac{1}{2}=0.5$

Therefore, the Equation of the line is y = 0.5x + 5.
