You need to graph them. It's rather hard to explain graphing, but I'll give it a shot. since we know one slope form is y=mx+b, and we have that form, it becomes more simple. So we have 3, which is the y-intercept. The y-intercept line is the line that goes up vertically. Plot a point on the three. So then, the equation, y=4x. SO say x is 1. Then, y would be 4.If x was two, y would be 8. Make sure to plot all of the points and draw a line through. Hope this helps!

What is the equation of a line that passes through the points (0, 5) and (4, 8)?

Andrew [12]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope - intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (4, 8)

m = $\frac{8-5}{4-0}$ = $\frac{3}{4}$

Note the line crosses the y- axis at (0, 5) ⇒ c = 5

y = $\frac{3}{4}$ x + 5 ← equation in slope- intercept form

Matt earned 28,500 last year. Paid 8,265 for rent. What percent did he pay for the rent

algol [13]

29%

If you put the amount he paid for rent (8,265) over the amount he earned (28,500), then you will get a decimal number.
8,265/28,500=.29
You then take this decimal and multiply by 100 to get the percent.
.29*100=29%
