Emily designed a robot that could climb down steps. She drew a graph to show the results from a test of her new robot. The graph

kifflom [539]

So youre a given two points. The points (0,15) and (150,0). First solve the slope of the graph

M = (y1 – y2) / (x1 – x2)

M= (15 – 0) / ( 0 – 150)

M = - 0.1

Using point (15,0)

15 = -0.1(0) + b

15 = b

So y = mx + b

Y = -0.1x + 15

Write the equation if the line that passes through (4,5) and has a slope of m=3

andrew11 [14]

Answer:

y = 3x - 7

Step-by-step explanation:

The <em>point-slope formula</em> for a straight line is

y – y₁ = m(x – x₁)

x₁ = 4; y₁ = 5; m = 3 Substitute the values

y – 5 = 3(x - 4) Remove parentheses

y – 5 = 3x - 12 Add 5 to each side

y = 3x - 7

The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
